Optimization of multi-element energy storage layout and zoning in oilfield power grid under high ratio distributed power source access

Abstract

Abstract Distributed power generation is a small-scale power generation system, which is distributed in an oil field power grid. In order to improve the poor effect of weak voltage nodes, a new partition optimization method of multi-energy storage layout in the oilfield power grid is proposed by introducing a high proportion of distributed power supply access. The investment and construction cost, the cumulative life cycle discharge loss cost, the operating income and the market income of electric energy are mined, and the model is constructed based on the mining results. The output results are input into the economic benefit maximization function to obtain the constraint conditions of the basic optimization objective function. Based on the constraints, the objective function of multi-energy storage system optimization is constructed, and the function is solved by a differential evolution algorithm to realize the partition optimization of multi-energy storage layout in an oil field power grid. Through experiments, it can be seen that the operation performance of the oil field power grid has been significantly improved through partition optimization of multi-energy storage layout under the condition of a high proportion of distributed power supply access. The experimental results show that the voltage fluctuation of the distributed power supply is small and that the self-absorption rate of photovoltaic power is high.
