Research on Energy Management Strategy of Isolated Microgrid with Photovoltaic Power Generation

Abstract

The globalized stone energy crisis and the climate and environmental crisis have promoted the adjustment and transformation of the energy industry structure worldwide. As a key area of the energy development strategy, the power industry will develop towards clean and efficient renewable energy. With the development of new material technology and control technology, the construction of micro-grid is bound to become a trend, and the large-scale development of micro-grid will affect the operation of the power grid, so the use of advanced control strategies and energy management technologies to improve the performance of micro-grid imperative. This paper first establishes the mathematical model of the independent micro-grid operation mode, and establishes the objective function from the constructed mathematical model. Then, through the improved genetic algorithm to coordinate and optimize the multi-objective. Finally, a micro-grid structure is built on the MATLAB platform to simulate the control strategy of the independent operation mode of the micro-grid. The experimental results show that the strategy proposed in this paper is feasible and correct for energy optimization of the independent micro-grid containing photovoltaic power generation Grid energy coordination and optimization improves the utilization rate of energy, maximizes the consumption of renewable energy, reduces the operating costs of micro-grids, and improves the comprehensive economic benefits of micro-grids.
