极端灾害下考虑VPP支撑的配电网供电恢复策略
Power Restoration Strategy for Distribution Network Considering VPP Support Under Extreme Disasters
摘要
Abstract
Sudden extreme disasters will cause failures in the distribution networks,leading to load outages and rising to safety issues and economic losses.To address these problems,this paper proposes a load power supply restoration strategy for the distribution networks considering the support of virtual power plants(VPPs),which improves the load restoration rate of the distribution networks through the coordination of the distributed generation(DG),loads and energy storage in the VPPs.First,a descriptive model is constructed for the DGs,load and storage resources inside the distribution networks and VPPs,with modeling conducted for photovoltaic systems,energy storage devices,shiftable loads,curtail able loads and transferable loads.Second,a load power supply restoration strategy for the distribution networks based on island partitioning is proposed.Under normal operation conditions,the distribution network doesn't enter the islanding mode and energy interaction with VPPs is realized with the minimum operation cost.In the event of extreme disasters,the distribution network operates in the multi-islanding mode with the optimization objective of minimizing the load restoration cost.Then,a calculation method for the load power supply restoration strategy of the distribution networks based on rolling optimization is put forward.When an extreme disaster occurs,the distribution network determines the supporting capacity of VPPs by formulating electricity purchasing and selling prices,thereby increasing the load restoration capacity of the distribution network.Finally,the proposed scheme is verified by simulation based on the improved IEEE 33 bus system.The simulation results show that the load loss of the distribution network is effectively reduced by using the proposed strategy.关键词
