【摘要】：传统的含风电场的输电网规划通常忽略运行成本或者运行状态对目标函数的影响,在风电场多点并网的情况下系统潮流分布波动显著,运行状态对运行成本的影响增大。同时,并网点风电与负荷的相关性对运行的经济性和可靠性有较大影响。本文建立含运行成本、建造成本、可靠性成本的多目标含风电场并网点优化的网源协调输电网扩展模型;采用聚类技术建立了计及风电空间分布的多维运行场景,通过多场景模拟运行,减少了计算量;采用多目标微分进化算法求解优化模型,利用熵权TOPSIS方法确定最优方案。以加入风电的IEEE30系统进行扩展与并网点优化,验证了空间多维场景技术与网源协同优化模型的适用性和有效性,为山区风电多点并网提供方法。
[Abstract]:The traditional transmission network planning with wind farm usually ignores the effect of operation cost or operation state on the objective function. In the case of multi-point grid connection of wind farm, the distribution of power flow fluctuates significantly, and the influence of operation state on operation cost increases. At the same time, the correlation between wind power and load has great influence on the operation economy and reliability. In this paper, the expansion model of multi-objective coordinated transmission network with wind farm and node optimization is established with operation cost, construction cost and reliability cost, and the multi-dimensional operation scenario considering the spatial distribution of wind power is established by cluster technology. The multi-objective differential evolution algorithm is used to solve the optimization model and the entropy weight TOPSIS method is used to determine the optimal scheme. Based on the expansion and parallel network optimization of IEEE 30 system with wind power, the applicability and effectiveness of spatial multi-dimensional scene technology and network-source cooperative optimization model are verified, which provides a method for multi-point grid connection of wind power in mountainous area.
