摘要
光伏发电发展迅速,其间歇性与波动性使传统机组频繁处于深度调峰状况,借助光热电站可有效缓解。从光伏光热发电特性出发,建立了光伏光热联合发电模型,并对其接入后的电力系统进行优化。以光伏光热联合系统的收益最大以及跟随负荷能力最大为目标,并采用权重法对目标函数进行处理,可知优化模型满足光伏光热电站的主要运行约束与传统安全约束。IEEE 30节点的算例结果证明了该模型的有效性与可行性。
Along with the fast development of photovoltaic(PV)power generation in China,the intermittency and volatility of fast developed photovoltaic power generation makes the traditional power generation units lying in the condition of depth peak load regulation,and such a condition could be effectively remitted by concentrating solar power(CSP)station.On the basis of the characteristics of PV power generation and concentrating solar power plant,a combined power generation model consisting of PV power generation and CSP generation was established,and the power grid connected with the established model was optimized.Taking the maximized earnings of PV power generation and CSP generation and the maximized capability to follow the load variation as the objectives and the objective function was processed by the method of weighting,thus it could be testified that the optimized model could satisfy main operational constraints of PV power generation and CSP generation as well as the traditional security constraints.Simulation results of IEEE 30-bus system show that the proposed model is effective and feasible.
