分布式风电源与配网联络线协调规划

为了充分利用风能，提高分布式风电源在配电网规划中的经济性和可靠性，提出一种分布式风电源(DWG)和联络线协调规划的方法。先通过分析DWG和联络线之间位置不同对供电可靠性的影响，提出了考虑DWG和联络线影响的事故负荷损耗指标 (CLLI)评估算法。在此基础上建立分布式风电源和联络线投资综合最小、网损最小以及供电可靠性最佳的多目标规划模型，应用非劣排序遗传算法优化得到分布式风电源的位置、容量和联络线的位置。IEEE33算例结果表明，该方法能得到合理的分布式风电源位置容量与联络线位置方案。

Coordinated allocation of DGs and tie lines in distribution networks

In order to make the best use of wind power and improve the economy and reliability of distributed wind generation (DWG) in the distribution network planning, a coordinated planning of tie lines and DWG is developed. First, by analyzing the influence of different locations of DWGs and the tie lines on the power distribution reliability, the contingency load loss index (CLLI) algorithm is proposed. On this basis, a multi-objective planning model is developed with a minimum DWG and tie line cost and network loss as well as the optimal reliability. The non-dominated sorting genetic algorithm is used to get the location and capacity of DWG and the location of tie lines. IEEE 33-bus system shows that the method proposed is reliable and effective in the determination of the location and capacity of DWG and the location of tie lines.
