Towards Optimal System Scheduling With Synthetic Inertia Provision From Wind TurbinesIEEE Transactions on Power Systems - Tập 35 Số 5 - Trang 4056-4066 - 2020
Zhongda Chu, Uros Markovic, Gabriela Hug, Fei Teng
The undergoing transition from conventional to converter-interfaced renewable
generation leads to significant challenges in maintaining frequency stability
due to declining system inertia. In this paper, a novel control framework for
Synthetic Inertia (SI) provision from Wind Turbines (WTs) is proposed, which
eliminates the secondary frequency dip and allows the dynamics of SI from WTs to
be analy... hiện toàn bộ

Quantum Annealing With Integer Slack Variables for Grid PartitioningIEEE Transactions on Power Systems - Tập 38 Số 2 - Trang 1747-1750 - 2023
Dawei Wang, Kedi Zheng, Fei Teng, Qixin Chen
Quantum annealing (QA) can be used to efficiently solve quadratic unconstrained
binary optimization (QUBO) problems. Grid partitioning (GP), which is a classic
NP-hard integer programming problem, can potentially be solved much faster using
QA. However, inequality constraints in the GP optimization model are difficult
to handle. In this study, a novel solution framework based on QA is proposed for... hiện toàn bộ

The available transfer capability (ATC) is an important parameter for all
companies participating in power transaction activities. The main objective of
this work is to propose a new methodology to determine the best points in the
system to add new agents (sellers and buyers), in order to maximize the ATC,
without violating a pre-established reliability level. In the process, the ATC
probability d... hiện toàn bộ

Modeling Frequency Dynamics in Unit Commitment With a High Share of Renewable EnergyIEEE Transactions on Power Systems - Tập 35 Số 6 - Trang 4383-4395 - 2020
Ziyang Zhang, Ershun Du, Fei Teng, Ning Zhang, Chongqing Kang
The power system inertia is gradually decreasing with the growing share of
variable renewable energy (VRE). This may jeopardize the frequency dynamics and
challenges the secure operation of power systems. In this paper, the concept of
frequency security margin is proposed to quantify the system frequency
regulation ability under contingency. It is defined as the maximum power
imbalance that the sy... hiện toàn bộ
