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

Market Mechanism Design of Inertia and Primary Frequency Response With Consideration of Energy MarketIEEE Transactions on Power Systems - Tập 38 Số 6 - Trang 5701-5713 - 2023

The shortage of inertia and primary frequency response (IPFR) will be more severe in future power systems since conventional fossil-based synchronous generators are gradually being replaced by variable renewable energy (VRE) generators. To relieve the shortage of IPFR, corresponding market mechanisms should be designed and incorporated to motivate appropriate provision from various sources. The me...... hiện toàn bộ

Towards Microgrid Resilience Enhancement via Mobile Power Sources and Repair Crews: A Multi-Agent Reinforcement Learning ApproachIEEE Transactions on Power Systems - Tập 39 Số 1 - Trang 1329-1345 - 2024
Yi Wang, Dawei Qiu, Fei Teng, Goran Strbac
Mobile power sources (MPSs) have been gradually deployed in microgrids as critical resources to coordinate with repair crews (RCs) towards resilience enhancement owing to their flexibility and mobility in handling the complex coupled power-transport systems. However, previous work solves the coordinated dispatch problem of MPSs and RCs in a centralized manner with the assumption that the communica...... hiện toàn bộ
