Configuration of Grid-Side Energy Storage Considering Voltage Timing Characteristics and Cycle Life
摘要
Abstract
Aiming at the problem of rough evaluation of voltage quality in distribution networks and the lack of consideration for improving system voltage quality and coordinating with reactive power compensation equipment through grid side energy storage,an optimized configuration method for grid-side energy storage is proposed that takes into account voltage timing characteristics,line loss,and operational economy of the distribution network.Firstly,the multi-attribute comprehensive evaluation index system of volt-age quality is established based on the three dimensions of bidirectional voltage exceeding the limits,fluctuation characteristic and time series trend.Secondly,the calculation method of energy storage cycle life is refined,and then the energy storage benefit model of grid side is put forward considering line loss and cycle life.Then,a two-layer model of energy storage optimization configuration is established.The upper layer maximizes the life cycle benefit of energy storage and optimizes its power and capacity.Aiming at the maximum comprehensive evaluation value of network voltage quality and the minimum operation cost of reactive power regulation equipment after storage allocation,the optimization model of the operation strategy of the storage power layer is established.Finally,a numerical example is designed to verify the effectiveness of the proposed model and method.关键词
