【摘要】：考虑分布式电源投资经济效益的基础上,建立以网络损耗费用、分布式电源发电售电收入、分布式电源投资与运行维护成本为目标的分布式电源规划模型,采用双向搜索机制的纵横交叉算法具有很强的全局收敛能力,但算法的竞争算子使粒子局限于"嫡系"粒子间的竞争,为保证粒子公平竞争,通过引入精英保留策略对纵横交叉算法进行改进,将改进的算法与IEEE69节点系统相结合进行仿真实验,所得结果表明改进算法优化结果准确、合理,算法的全局搜索能力强,收敛精度高。
[Abstract]:On the basis of considering the economic benefits of distributed power investment, a distributed power planning model is established, which aims at the cost of network loss, the revenue from electricity sale of distributed generation, the investment of distributed power and the cost of operation and maintenance. The vertical and horizontal crossover algorithm with bidirectional searching mechanism has strong global convergence ability, but the competition operator of the algorithm limits particles to the competition between "direct" particles, in order to ensure fair competition of particles. Through the introduction of elite retention strategy to improve the crossbar algorithm, the improved algorithm is combined with the IEEE69 node system for simulation experiments. The results show that the improved algorithm optimization results are accurate and reasonable. The algorithm has strong global searching ability and high convergence accuracy.
