Research on Locating and Sizing Optimization of Distributed Power Based on Security

分布式电源的发展是我国智能电网发展中的重要方面之一,基于安全保障性,合理地对分布式电源进行选址定容,对于中低压配电网规划具有重要意义。分析了分布式电源对配网的具体安全性影响。提出以安全第一、成本最小、网损最小、电压偏移最小为目标的综合效用目标函数模型,并采用遗传算法求解。通过对IEEE9节点配电网络的算例分析验证了所提算法在分布式电源选址定容求解问题中的可行性和实用性。

Distributed generation is one of the most important topics in the development of smart grid. Reasonable location and capacity for distributed generation is of great significance to distribution network planning. This paper analyzes the specific influence of distributed generation on distribution network. Aimed at safety first, cost lowest, network loss least and minimum voltage deviation, the comprehensive target model is put forward and the genetic algorithm is adopted to improve the location and capacity analysis. Finally the IEEE9 distribution network is analyzed to verify the feasibility and practicability of the proposed genetic algorithm in the optimal location and capacity.
