Abstract
With the continuous growth of energy consumption and the increasingly prominent environmental issues,the integrated development of photovoltaic power generation and energy storage systems has become an important way for energy-saving and emission reduction in the power system.A set of energy-saving control strategy system on the power supply side is proposed,covering power prediction and evaluation based on long short-term memory network(LSTM),energy-saving control algorithm based on multi-objective optimization,energy storage scheduling strategy based on peak-valley electricity price and multi-mode coordinated control method.A system operation cost model is constructed,and an energy-saving objective function to minimize the total operation cost is proposed.Taking the implementation of a photovoltaic energy storage system in a certain industrial park as the research object,a 3.3 MW photovoltaic system and a 1.3 MWh energy storage system are configured.The results show that this strategy has enabled the utilization rate of photovoltaic power generation to reach 98%,maintained the charging and discharging efficiency of the energy storage system above 90%,reduced the comprehensive energy consumption of the industrial park by 12%,achieved an annual net income of 2.8 million yuan,and had an investment payback period of 4.2 a.关键词
