Network-constrained multiperiod auction for a pool-based electricity marketIEEE Transactions on Power Systems - Tập 17 Số 3 - Trang 646-653 - 2002
A.L. Motto, F.D. Galiana, A.J. Conejo, J.M. Arroyo
This paper presents a multiperiod electricity auction market tool that explicitly takes into account transmission congestion and losses as well as intertemporal operating constraints such as start-up costs, ramp rates, and minimum up and down times that may be included in any generating unit's composite bid. This approach, which requires only existing mixed-integer linear solvers, provides the mar...... 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

Stochastic Scheduling With Inertia-Dependent Fast Frequency Response RequirementsIEEE Transactions on Power Systems - Tập 31 Số 2 - Trang 1557-1566 - 2016
Fei Teng, Vincenzo Trovato, Goran Strbac
High penetration of wind generation will increase the requirement for fast frequency response services as currently wind plants do not provide inertial response. Although the importance of inertia reduction has been widely recognized, its impact on the system scheduling has not been fully investigated. In this context, this paper proposes a novel mixed integer linear programming (MILP) formulation...... 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
Kexin Li, Hongye Guo, Xichen Fang, Shuangquan Liu, Fei Teng, Qixin Chen
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

Voltage Stability Constrained Unit Commitment in Power Systems With High Penetration of Inverter-Based GeneratorsIEEE Transactions on Power Systems - Tập 38 Số 2 - Trang 1572-1582 - 2023
Zhongda Chu, Fei Teng
With the increasing penetration of renewable energy sources, power system operation has to be adapted to ensure the system stability and security while considering the distinguished feature of the Inverter-Based Generator (IBG) interfaced generators. The static voltage stability which is mainly compromised by heavy loading conditions in conventional power systems, faces new challenges due to the l...... hiện toàn bộ

Resilient Secondary Voltage Control of Islanded Microgrids: An ESKBF-Based Distributed Fast Terminal Sliding Mode Control ApproachIEEE Transactions on Power Systems - Tập 36 Số 2 - Trang 1059-1070 - 2021
Pudong Ge, Yue Zhu, Tim C. Green, Fei Teng
This paper proposes a distributed secondary voltage control method based on extended state Kalman-Bucy filter (ESKBF) and fast terminal sliding mode (FTSM) control for the resilient operation of an islanded microgrid (MG) with inverter-based distributed generations (DGs). To tackle the co-existence of multiple uncertainties, a unified modelling framework is proposed to represent the set of differe...... 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
