Power Flow Optimization of Flexible Active Distribution Network Based on Photovoltaic-energy Storage SNOP
摘要
Abstract
In recent years,the soft normally open point(SNOP)based on modern power electronic devices has gradually become an important part of the distribution network.In order to take full advantages of the topology of SNOP,it is proposed to connect the photovoltaic-storage integrated system on the DC side of SNOP to optimize the power flow of distribution network.Firstly,the models of energy storage system and photovoltaic system are analyzed,and they are connected to the DC side of SNOP to form an SNOP integrated with photovoltaics and energy storage(PE-SNOP).Secondly,on this basis,the power flow regulation model of flexible active distribution network is established,which utilizes second-order cone programming algorithm to solve the problem.Finally,the proposed optimization model and algorithm were solved and verified on an improved IEEE 33-node system,and compared with the optimization results obtained from SNOP and intelligent energy storage switch.The results indicate that the proposed model can effectively improve the regulation ability of SNOP,achieve peak shaving and valley filling,suppress random disturbances,and improve the performance of the system,thereby boosting the economy of distribution network operation.关键词
