为了实现微电网运行的可靠性和经济性,对其进行能量优化管理是微电网运行的关键。提出一种基于改进粒子群算法的微电网能量管理模型,改进算法重点在于提出一种寻找可行解方法,将可行解作为粒子群初始位置,并使用步长加速法对部分可行解进一步搜索得到更优解。通过一个直流微电网验证了所提模型的有效性,算例运行结果表明,所提模型在不同能量管理策略下实现了微电网运行的可靠性和经济性。
In order to achieve the reliability and economy of microgrid operation, optimizing energy management is the key to the operation of microgrid. An improved particle swarm optimization algorithm based on improved micro-grid energy management model is proposed. The key point of the improved algorithm is to find a solution to the feasible solution, using the feasible solution as the initial position of the particle swarm and using the step-acceleration method to further search some feasible solutions Excellent solution. The validity of the proposed model is verified by a DC microgrid. The results of the example run show that the proposed model achieves the reliability and economy of microgrid operation under different energy management strategies.
