Optimal Allocation of Energy Storage in Centralized Power Generation Scenarios Considering Photovoltaic Working Conditions
摘要
Abstract
The large-capacity energy storage technology can alleviate the impact of grid-connection of photovoltaic ( PV ) power stations on the power system and solve the problem of large-scale PV power abandonment.However,in the energy storage allocation process of new energy at present,only the optimal energy storage capacity on typical days is considered,and the impact of fluctuations of PV output under different working conditions on the energy storage scale is ignored.In view of these problems,an optimal allocation method for PV and energy storage considering PV working conditions is put forward.The density peak clustering algorithm is used to cluster all the PV output operation scenarios,thus forming a typical scenario under different PV conditions.On this basis,the capacity and power of energy storage are allocated,respectively.In addition,the allocation of energy storage power and capacity is performed on the basis of the annual PV output and typical daily output.The annual output allocation results are taken as a benchmark,and the above three allocation methods are compared to verify the rationality and effectiveness of the proposed method.Moreover,the energy storage output in its life cycle is analyzed through simulations of an example.关键词
