在电力市场环境下,市场竞争带来的潮流运行方式的随机性、多变性和不可预测性与输电网的潮流约束、安全约束相互矛盾而又同时存在,从需求侧角度考虑,针对Pool模式电力市场中需求侧各购电成员之间利润分配的非合作博弈均衡问题,提出了多个需求侧购电成员如何优化自己的购电竞价策略而使所有购电者均达到收益最大化的2层优化模型,考虑了电力网络约束对购电成员收益的影响,针对此均衡约束数学规划问题提出了一种求解多个需求侧购电成员处于纳什均衡点的最优策略解析方法,同时还提供了从备选策略集合中找到纯纳什均衡解的方法,在此基础上,以IEEE 30节点系统为例说明需求侧采用购电策略报价对发电商收益、需求侧各自收益及对电力市场运行的影响。
In the electricity market environment, the randomness, variability and unpredictability of the tidal current operating mode brought by the market competition and the tidal current constraints and the safety constraints of the power transmission network are contradictory and simultaneous. From the demand side, The problem of non-cooperative game equilibrium of profit distribution between demand-side members in the market and two layers of how multiple demand-side electricity purchasers optimize their own bidding strategy so that all the consumers are maximized In order to solve this problem of equilibrium constrained mathematic programming, an optimal strategy analysis method for solving the problem of multiple demand-side purchase members at Nash equilibrium points is proposed. The optimal model is also considered. Based on this, taking the IEEE 30-bus system as an example to illustrate the effect of demand-side pricing strategy on the returns of generators, the demand side’s demand and the power market operation .
