Economic operation research for wind-PV-ES hybrid micro-grid

摘要

This paper researches economic operation of wind-PV-ES hybrid micro-grid. Firstly, operational strategy of micro-grid and its energy system are proposed. Then the economic operation optimization model is built and particle swarm optimization algorithm is simulated with MATLAB. Based on a practical wind-PV-ES hybrid micro-grid, the simulated results give the optimization cost according to the load and wind power/PV output prediction under kinds of typical weather condition. The results comparison shows that the proposed optimization method is useful to reduce operational cost.
