Title: Efficient Eigen-analysis of Grid-connected MMC Characterized by
Linear Time-Periodicity
Abstract: The linear time-periodic (LTP) theory
is essential to the stability assessment of the grid-connected modular
multilevel converter (MMC) system with multiple harmonic components in steady
state. Based on the Floquet theory, this paper presents a semi-analytical
expression for the system state transition matrix over a period (that is, the
monodromy matrix) of LTP system based on the Chebyshev collocation method.
Specifically, an explicit expression for the system state after a period is
derived in terms of the initial condition, whose coefficient matrix is the
approximated monodromy matrix. Its eigenvalues, i.e., Floquet characteristic
multipliers, have high accuracy. Compared with the commonly-used time-domain
integration method, the presented method obtains greater efficiency by avoiding
numerically integrating the studied system itself.

Title: Utilizing Demand-side Generalized Energy Storage to Decarbonize Future
Smart Cities
Abstract: Our modern urban power system is experiencing the Third Energy
Revolution that features the integration of high penetration of renewables,
e.g., wind and solar. However, renewable generation is known to be intermittent
and stochastic which cannot match the electricity demand well. This “mismatch”
may significantly deteriorate the security operation of power systems. Widely
installing energy storage systems is a possible solution; but is extremely
expensive. This talk discusses how existing & cheap demand-side resources can be
utilized as generalized storage systems to balance the electricity supply and
demand, which will further promote the integration of renewables and decarbonize
our future smart cities.

Title: Virtual Collection Technology for Distributed PV Data Empowered
by Artificial Intelligence
Abstract: In recent years, with the rapid
development of distributed photovoltaic systems (DPVS), the shortage of data
monitoring devices and the difficulty of comprehensive coverage of measurement
equipment has become more significant, bringing great challenges to the
efficient management and maintenance of DPVS. For this reason, it is crucial and
beneficial to develop a cost-effective and computationally efficient data
collection method for large-scale DPVS clusters with relatively small numbers of
sensing devices deployed at strategic locations. Virtual collection is a new
DPVS data collection scheme we propose, whose core idea is to use the power data
of selected reference power stations (RPSs) in the region as input to infer the
power data of other stations through artificial intelligence algorithms. If
deployed at strategic locations with proper redundancy, the reduced sensing
network can still provide low-cost yet highly sufficiently accurate measurements
of the DPVS networks for various power operations.

Title: A Physics-informed Deep k-medoid Scenario Clustering Method for
Transmission Network Expansion Planning
Abstract: Transmission network expansion planning
(TNEP) is driven to consider far more scenarios than ever as the diversity of
injections into power systems increases significantly with the ever-increasing
penetration of renewable energy. By selecting a representative scenario subset,
scenario clustering is more and more important to realize the computational
feasibility of TNEP, which aims at ensuring the TNEPs over the full scenario set
and over the subset have the same line addition strategies. In this study, we
focus on k-medoid scenario clustering, which quantifies dissimilarities between
scenarios by Euclidean distance in a certain clustering space. However, because
of the obscure relationship between injections and the line addition strategies,
how to define the clustering space and whether Euclidean distance is suitable to
measure the dissimilarity are still left open. Herein, we formally give
sufficient conditions (SCs) for the clustering aim accomplishment. Then, using
multi-parametric mix-integer linear programming (mp-MILP), we disclose the
non-linear relationship between injections and the line addition strategies and
show the input space, where the injection data lies, is not qualified for the
clustering space. Because of the difficulty of a pure physics-based method to
define a suitable clustering space, we establish a deep k-medoid clustering
network (DKCN) and transform the SCs into a physics-informed loss function
(PLF). Driven by the PLF, a clustering space is found by the DKCN, which not
only satisfies the SCs but also ensures Euclidean distance is suitable. Finally,
an analytical condition is provided which guarantees the clustering aim can be
achieved if k-medoid scenario clustering is taken place in the clustering space
found by the DKCN.

Title: Learning From and Surpass Human Demonstrations: A Hybrid
Augmented Intelligence Approach For Multi-stage Power Dispatch
Abstract: The low learning efficiency and
feasibility hinder practicability of artificial intelligence based power
dispatch. We introduce a hybrid augmented intelligence approach to tackle
multi-stage power dispatch under uncertainty. Firstly, inverse reinforcement
learning with trajectory ranking is employed to deduce the latent reward
function from human demonstration. Then, expert demonstrations guided learning
is proposed. Behavior cloning is adopted to transfer human knowledge into guided
policy. This policy is used to guided RL dispatcher to a safe and fast learning
process at the early stage, which avoids frequent trial and error. A smooth
switch mechanism then is applied which allows RL to conduct free exploration to
seek for better policy surpassing expert demonstrations. Finally, numerical
results are discussed.

Title: The Application of Traveling Wave Wideband Feature:
Identification of Fault Induced Traveling Wave in Complex Multi-section Grid
Abstract: As the speedy expansion of power gird,
the traveling wave fault locator in substation may not always connect to newly
added transmission lines in time, which reduces the effectiveness of fault
locator. In this research project, an adjacent fault-free line based fault
location scheme for newly additional line is proposed. Since the traveling wave
from adjacent fault-free line results in severe difficulty for identification of
traveling waves from faulty line, the time-frequency matrix is performed to
screen traveling waves. Firstly, in order to remove the influence of waves from
remote terminals of adjacent fault-free line, the current refraction coefficient
is theoretically analyzed. Due to the negative refraction coefficient, traveling
waves from remote terminals of adjacent fault-free line can be reduced by the
proposed composite traveling wave. Secondly, the time-frequency matrices of
composite traveling wave and original traveling wave is obtained by S-transform.
Then, these matrices are applied to form ratio matrix which thoroughly
eliminated waves from remote terminals of fault-free lines. Moreover, the
robustness of the proposed fault location scheme is thoroughly validated by the
simulation of PSCAD/EMTDC. Finally, the proposed fault location method has the
great accuracy in simulation tests and field data test.
