电力市场环境下系统运行安全性的优化问题

保障合理的系统运行安全性有利于总体电价的降低。对于不同的市场体制,提出了基于社会效益最大化和在不影响电网公司用户经济利益前提下的电网公司效益最大化两种安全性优化方法的数学模型,并给出了一种简化实用算法。在新的辅助服务优化模型中,网络结构、运行方式、辅助服务价格、停电损失、切负荷赔偿价格及所考虑的安全性校验措施等因素均将对辅助服务的购买产生影响,从而影响系统运行的安全性。经仿真验证,该方法是可行的。

Optimization of the Power System Operation Security in Power Market Environment

It is favorable to the reducing of the power rate to keep a reasonable security of the power system operation.For the market regimes of maximum social benefits and maximum the grid company's profits,the paper proposes respectively two kinds of optimal security models and a kind of practical algorithm.In the new models,the network structure,the operation mode,the ancillary service price,the outage loss and the loadshedding price have influenced on purchase of the auxiliary service,and then influenced the systematic operation security.The simulated results of a reliability test system show that the method is feasible.
