Title: Distributed Control of Energy Storage Systems for Power System Frequency and Voltage Regulation
Abstract: The penetration of renewable energy in the power grid has significantly impacted the grid’s frequency and voltage stability. The energy storage system (ESS) based grid frequency and voltage regulation scheme has become a feasible solution. By optimally allocating the ESSs in the wind farm (WF), the overall frequency support capability of the WF can be enhanced, even in the presence of wake effects or individual turbine operation difference. Moreover, the coordinated ESSs are regulated by the distributed consensus controller such that they can collectively respond to frequency violation situations, and maintain high coherence in state-or-charge across the whole time frame. For the power distribution network, the ESSs find their application in mitigating the issue of overvoltage caused by reverse power flow, while maintaining serving as frequency responsive units. A novel consensus control scheme called containment control is applied for the ESSs, where the mission of voltage regulation and frequency control are treated as two vertical control objectives, and can be achieved via a single control mechanism.

Title: Enhancing Urban Grid Resilience based on Massive Building Flexibility Resources
Abstract: The lack of flexibility resources and coordination capabilities in urban grids limits resilience, particularly in terms of rapid recovery after disasters. The vast number of buildings in cities harbors significant flexibility resources; for example, virtual energy storage can be achieved through the thermal capacity of buildings and their HVAC systems. When aggregated, these resources provide substantial capacity, a wide modulation range, and quick response times, enhancing the spatiotemporal coordination of various resources and offering new opportunities and methods for improving urban grid resilience. The presenter will introduce their research on building-grid interaction flexibility and enhancing power system resilience, focusing on: experimental studies and data analysis of commercial building load responses; energy efficiency analysis and improvement methods for HVAC systems participating in grid ancillary services; post-disaster recovery methods for urban grids utilizing spatiotemporal flexibility from HVAC systems based on deep reinforcement learning; and a resource trading method to alleviate the "duck curve" using distributed Nash bargaining theory to incentivize building-grid interaction flexibility.

Title: Deep Reinforcement Learning for Smart Electric Vehicle Charging
Abstract: Aggregating a large volume of electric vehicles (EVs) can provide considerable capacity for frequency regulation (FR) services. However, disaggregating real-time FR commands to individual EVs results in both immediate impacts to EVs and cascading impacts on future FR bidding. It is crucial to manage the trade-off between these two impacts during disaggregation. This paper proposes a deep reinforcement learning (DRL)-based FR provision method that balances user charging anxiety and aggregate flexibility in real-time disaggregation. The immediate and cascading impacts of disaggregation are modelled through two objectives: 1) user compensation costs related to charging anxiety, and 2) the preservation of EV aggregate flexibility. Incorporating these two objectives, a multi-objective disaggregation optimization problem is formulated with a learnable soft switching factor to balance these objectives. To determine the optimal soft switching factor and achieve coordination between bidding and disaggregation, the reinforcement learning algorithm is utilized to jointly optimize biddings and the soft switching factor.

Title: Capacity Expansion of High Renewable Penetrated Energy Systems Considering Concentrating Solar Power for Seasonal Energy Balance
Abstract: With the increasing proportion of variable renewable energy which owns fluctuation characteristics and the promotion of the “Clean Heating” policy, the seasonal energy imbalance of the system has been more and more challenging. There is a lack of effective means to mitigate this challenge under the background of gradual compression of the traditional thermal unit construction. Concentrating solar power (CSP) is a promising technology to replace thermal units by integrating emergency boilers to cope with extreme weather, and can meet long-time energy balance as a seasonal peak regulation source. In this paper, we propose a long-term high-resolution expansion planning model of energy systems under high renewable penetration which integrates CSP technology for seasonal energy balance. By taking the energy system in Xinjiang province which is a typical area of the “Clean Heating” project with rich irradiance as a case study, it shows that the optimal deployment of CSP and electric boiler (EB) can reduce the cost, peak-valley difference of net load and renewable curtailment by 8.73%, 19.72% and 58.24% respectively at 65% renewable penetration compared to the base scenario.

Title: Resilience Enhancement Techniques for Integrated Energy Systems Against Extreme Events
Abstract: The increasing frequency of extreme events poses severe challenges to the security of integrated energy systems (IES). To enhance IES resilience against extreme events, we focus on three critical dimensions: resilience assessment, resilience planning, and resilience restoration, to develop effective resilience enhancement strategies. Firstly, we propose a resilience assessment method for IES. In this work we analyze the specific impact of gas and heat inertia on IES resilience, and identify system vulnerabilities arising from multi-energy interdependencies. Then, we introduce a resilient-oriented IES planning method from an economic-risk balancing perspective, to improve system resistance against extreme events. Finally, we present an energy supply restoration method for IES considering multi-stage and multi-energy coordination, to develop IES emergency response and critical load restoration strategies after extreme events. The goal is to provide technical support for improving IES resilience and ensuring energy security during emergencies.

Title: Trading mechanism for social welfare maximization in integrated electricity and heat systems with multiple self-interested stakeholders
Abstract: Cooperation across multiple energy sectors is capable of maximizing social welfare as revealed by existing research, but such holistic dispatch can be hardly implemented in a reality where energy sectors are run by different stakeholders respectively. To fill this gap, energy trading among multiple self-interested stakeholders is investigated in this paper. To maximize the social welfare of the trading results, an effective pricing method, referred to as network-constrained generalized locational marginal prices, is proposed. A trading mechanism is then carefully designed to encourage stakeholders to trade at network-constrained generalized locational marginal prices, while economic properties of the resultant generalized Nash equilibrium are analyzed in depth. The effectiveness of the mechanism is validated in two integrated electricity and heat systems with different scales. Numerical comparison demonstrates that existing non-cooperative mechanisms may result in undesirable deadweight losses, while surplus sharing is a tricky issue in cooperative mechanisms, making the cooperation unstable and infeasible. On the contrary, each stakeholder may optimize its subsystem in a self-interested manner in the proposed mechanism, but the overall outcome strikingly coincides with social welfare maximization.

Title: Nonlinear control approach for direct-drive wave energy conversion systems
Abstract: The wave energy is regarded as the most prominent marine energy form and an essential part of the offshore renewable energy. The direct-drive wave energy conversion system (DDWECS) is widely used in practical projects due to its superior configuration and significant operational efficiency. The DDWECS adopts direct-drive power takeoff technique with a liner permanent magnet generator (LPMG). Nonlinear adaptive controller is developed for effective coordination in the grid-connection operation with supplementary energy storage system (SESS) due to its distinct intermittency characteristics. Firstly, feedback linearization technique is implemented in the generator-side converter controller, grid-side converter controller and SESS-side converter controller. Then, the specific coordination scheme among multiple converters is proposed considering various conditions. Finally, the improved dynamical responses of the DDWECSs with the proposed control strategies are demonstrated under Matlab/Simulink simulation environment. The current research results are illustrated and discussed.

Title: Evolutionary Game Strategies Investigation for Government and Corporate Participation in Wind and Photovoltaic Project Investments Driven by the Carbon Market
Abstract: Under the "Carbon Peak and Carbon Neutrality" policies, China is actively promoting the development of renewable energy projects while gradually establishing and improving its carbon trading mechanism. A key question that arises is how different stakeholders in the electricity market, particularly the government and enterprises, will adjust their behaviors in response to carbon market drivers, and what patterns emerge from these adjustments. In this context, this study investigates the investment game strategies between government and enterprises in wind and solar power projects, considering the influence of the carbon market. The study first provides an overview of the carbon market, the carbon trading mechanism, and the current status of China's renewable energy development. It then reviews the application of evolutionary game theory in the power and clean energy markets. To model the investment behaviors of government and enterprises, evolutionary game theory is employed, with a focus on two-population and three-population models. The study explores the evolutionary stability of different strategies and the conditions for equilibrium. Additionally, multiple rounds of simulations are conducted to analyze the sensitivity of key parameters, such as government subsidies and carbon pricing. The relationship between average expected returns and strategic choices is also examined, offering new insights into the investment behavior of stakeholders in wind and solar projects under the carbon market's influence.

Title: Research on optimal operation and control of AC/DC hybrid distribution systems with integration of high-ratio distributed generations
Abstract: Large-scale grid integration of distributed generations is an important measure to accelerate the construction of novel power systems. As a key link between the transmission power system and the distribution system, AC/DC hybrid distribution system will play an important role in the process of absorbing distributed generations. The distributed generations have strong randomness and volatility, and there is space-time imbalance between the load and the supply, and the uncertainty increases in the process of power generation balance and real-time scheduling, which affects the operation economy of the system. On the other hand, the characteristics of "high proportion of power electronic equipment" are becoming more and more obvious, and the moment of inertia and damping are constantly reduced, threatening the safe and stable operation of the system. In view of the above hot issues, combining our latest research progress, this report will first put forward a new type of source-network-load-storage cooperative operation technology. Secondly, the coordination control technology of multiple converters in AC/DC hybrid distribution system is discussed. Then, the local control technology of energy storage units and converters in distribution system is deeply studied. Finally, the future development direction of the AC/DC hybrid distribution system with integration of high-ratio distributed generations will be discussed so as to contribute to the communication and sharing of research results in the field of novel power system.

Title: Effect of Grid Forming and Grid Following Control on Firewall Capability of MMC-HVDC Systems
Abstract: The control methods of MMC-HVDC affect the inherent “Firewall” capability, leading to concerns over fault and oscillation prevention from one AC grid to another. We presented a thorough small signal stability comparative analysis between grid following control and grid forming control of a point-to-point HVDC-MMC system, focusing on the key control parameters and short circuit ratio impact on firewall capability. The small signal model of the study system is validated by the electromagnetic transient simulations in MATLAB/Simulink. Based on the small signal model, the grid voltage and current oscillation prevention threshold have been identified through eigenvalue analysis and participation factors. The ranges of critical control parameters and short circuit ratio that significantly contribute to the instability of the MMC-HVDC system are shown in heat maps, which is a valuable guidance for parametric selection and adjustment in practical engineering.

Title: Dynamic Digital-modeling and Loss-of-excitation Fault Protection Technology of Large Double-fed Variable Speed Pumped Storage Unit
Abstract: This study addresses the dynamic modeling, simulation, and fault protection of variable-speed pumped storage units (VSPSUs) connected to the grid, focusing on accurately capturing their operational characteristics to enhance system reliability. It first develops a dynamic simulation model for VSPSUs, reflecting their fault characteristics and dynamic behavior. The model, built using Matlab/Simulink, was validated through comparisons with real operational data. The research also examines symmetrical demagnetization fault characteristics, distinguishing between symmetrical and asymmetrical demagnetization by comparing DC and AC excitation systems. For symmetrical faults, a dropping impedance circle criterion for generator-side faults and a DC voltage criterion for grid-side faults were proposed. Simulations confirmed the reliability of these protection methods, offering valuable insights into improving fault detection and system protection for VSPSUs.
