【 摘 要 】

This paper established a Micro-grid model with wind turbine, photovoltaic cell, storage batteries and conventional loads. Under the conditions of wind and light load, the average power can be predicted formulated the optimal dispatch strategy with the optimal load price as the goal considering the use of wind, light and the battery in the model. The problem can be simplified as a mixed integer programming problem using two stage search algorithm to solve. For the first stage, the simulated annealing (SA) algorithm to search wind, light use factor and battery charge and discharge strategy. In the case of battery charge and discharge, in the second stage pattern-search algorithm is used to solve the optimal charging and discharging power to find the global optimal solution. Comparing the results of the optimization model with the single scheduling model, it has better economic performance.
