Economic Operation Optimization for New Energy Microgrid Based on Deterministic Method

In view of the typical application scenarios of microgrid, the mathematician rules of prediction errors for photovoltaic power, wind power and load are analyzed. With consideration of environmental protection and economic factors, an economic operation optimization model of microgrid based on deterministic method is constructed, which simplifies the difficulty for multi-objective problem solution. In a specific example, the influences of different confidence levels, different prediction errors and different environmental penalty factors on the microgrid operation are analyzed. The result shows that improving the prediction accuracy of photovoltaic output, wind power output and load can reduce the operation cost of microgrid. Moreover, the deterministic method has advantages of fast convergence speed and short iteration time for solving the optimization model of microgrid.
