摘要
中国风力资源分布集中且远离电力负荷中心,大规模风电的消纳已经成为制约风电从量向质升华的关键问题。而风电与常规能源联合外送作为消纳风电的有效方式已经进入实践阶段。为了研究外送中风电与火电的协调调度、利益分配问题,文中以能源互补外送系统的利润最大化为目标,分别构建了联合外送模式与独立外送模式的调度优化模型,并通过GAMS软件进行优化。基于联合外送与独立外送模式的利润水平,按Shapley值法对能源互补系统中的机组进行利润分配。分析结果表明,利润分配模型充分结合了风电与火电在整个系统中的贡献度进行公平分配,有利于引导风电与火电参与联合外送。
Majority wind resources in China are concentrated in the places that are far away from the load centers.Meanwhile,accommodation of large-scale wind power has become the key constraints for the wind energy generation developing from quantity to quality.As one effective way of wind power grid connection,joint delivery of wind power and conventional power to other regions has entered the practical application stage.In order to study the coordinated dispatching and profit distribution of wind power and thermal power during the joint delivery,dispatching optimization models of joint delivery mode and independent delivery mode of wind power and thermal power are developed respectively with the goal of maximizing the profit of energy complementary delivery system,and the models are solved by GAMS software.Profits of different units of the energy complementary system are distributed by Shapley value method based on the profit level of different modes.The analysis results show that the profit distribution model realizes the equitable distribution of the profits among the units of wind power and thermal power fully based on their contribution in the whole system,and is effective to encourage the participation of wind power and thermal power in joint delivery.
