Research on environmental and economic dispatch of microgrid based on coevolutionary genetic algorithm

摘要

The drawbacks of high cost, high pollution, and high energy consumption of traditional power system become increasingly apparent, so the energy crisis and energy conservation is an urgent requirement to promote new energy generation and renewable energy generation such distributed generations to become a useful supplement for main grid. And the microgrid is an effective way to access grid for the distributed power. Coevolutionary genetic algorithm has the characteristics of parallel computing, fast convergence, and strong optimization ability, which is applied into the optimization of environmental and economic dispatch of microgrid. By the minimum total costs of power generation and emission as target respectively in isolated mode and grid-connected mode, the optimal scheduling of distributed power contribution is achieved. The experimental results show the method is correct and effective.
