The invention discloses a photovoltaic power station energy storage configuration selection method with economical efficiency taken into consideration. The method includes the following steps of establishing an energy storage cost function model without considering the electricity price cost, judging the relation between the discarded electricity quantity and the annual energy output of an energy storage system on the basis of the energy storage cost function model according to the electricity limitation scheduling situation, inputting the relation between the discarded electricity quantity and the annual energy output of the energy storage system into a matlab tool to be calculated in an optimal mode, and obtaining the optimal photovoltaic energy storage matching ratio according to the calculation result. By comprehensively considering the technicality and the economical efficiency, analyzing the feasibility of photovoltaic energy storage combined running and putting forward a practical configuration scheme, the aim of improving the use economical efficiency is achieved.
Description
technical field [0001] The present invention relates to the field of configuration selection of photovoltaic energy storage capacity, in particular to a method for selection of photovoltaic power station energy storage configuration considering economy. Background technique [0002] Photovoltaic power generation is intermittent, volatile and random, and energy storage devices play an important role in photovoltaic power stations, especially large-scale photovoltaic grid-connected power stations. Energy storage devices can effectively maintain system stability, ensure energy backup, and improve power quality and reliability. However, due to the high price of energy storage, the configuration of energy storage in photovoltaic power plants may not always achieve good economic benefits. Existing related patents mainly involve the design of solar-storage combined system, the coordinated control method of combined solar-storage grid-connected power generation, and the configuratio...
