Research on simulations and model of the isolated Wind-Solar-Diesel-Battery hybrid micro-grid

The disturbance defending ability of the isolated micro-grid is weak, and the randomness and the weak controllability of new energy generation are harmful to system stability. So a completed and accurate model of the isolated micro-grid is needed to do research on key technologies. This paper proposes an operating mode for the isolated micro-grid. A PSCAD simulation model of the isolated micro-grid with wind-solar-diesel-battery hybrid power generation is built based on the operating mode. The model parameters are obtained by parameter identification method. The feasibility and the effectiveness of the proposed approach are proved by simulation and model of an island planning micro-grid.
