考虑极端事件的电力系统惯量与一次调频备用联合规划配置方法
A Joint Planning and Configuration Method for Power System Inertia and Primary Frequency Regulation Reserve Considering Extreme Events
摘要
Abstract
The traditional frequency response reserve planning involves the inertia in primary frequency regulation(PFR)resources,which fails both to meet the system inertia demand under the new situation and to realize the joint planning of inertia and PFR reserve.Meanwhile,neglecting the decision maker's risk preference may lead to homogenized patterns of extreme eventsand lay potential security threats.A joint planning method of inertia and PFR reserve considering extreme events is proposed.The system frequency response model with multiple types of source-storage-load regulation resources is established.The system disturbance set is obtained by using sequential Monte Carlo probabilistic production simulation.The penalty model is constructed to measure the loss of rate of change of frequency(RoCoF)overrun.The frequency stability probability index is proposed to characterize the probability distribution and loss expectation of frequency limit violation.The cost benefit model of reserve with risk preference is developed for collaborative planning and allocation of multiple flexibility resources,and the feasibility of planning solutions is verified.Based on the improved IEEE-RTS79 case studies,it is demonstrated that the proposed method can flexibly formulate the optimal planning under different risk ranges according to the decision maker's risk preference,providing a more targeted decision-making basis for improving the new power system's response capability to extreme events.关键词
