Power Restoration Method of Distribution Network with ESS and DG
2021 IEEE IAS INDUSTRIAL AND COMMERCIAL POWER SYSTEM ASIA (IEEE I&CPS ASIA 2021)(2021)
摘要
A restoration method of distributed power supply in power grid with energy storage system is proposed. First, it introduces the principle of distributed access and operation constraints of ESS and DG in the distribution network. Utilizing the parallel coordination and information interaction between independent and peer intelligent terminals in the distribution network, the power restoration method is adopted, which mainly includes two parts: distributed network topology search and expression and calculation of constraints on power restoration. It not only exerts the advantages of ESS in power restoration, but also avoids the problems of large amount of information collection and large amount of calculation in the centralized power restoration method in the distribution network. At the same time, consider the ESS power control adjustment strategy to achieve reasonable power support for the distribution network to expand the scope of power restoration in the power outage area. The simulation results of the IEEE33-bus system example verify the flexibility and effectiveness of the proposed method.
