电力市场中存在多个竞标者 ,既“牵一发而动全局”,又非一个或几个竞标者可完全左右市场行为 ,因而 ,市场问题实际上是复杂的系统工程问题。文中通过研究 PX( power exchange)搓合交易机理 ,探讨了市场电价的形成机制 ,建立了市场电价的数学模型 ,导出了电力公司改变竞标策略对PX市场电价影响的公式。数据仿真结果清晰反映出非管制电力市场的运行中 ,电力公司改变竞标策略对 PX市场电价和成交电量的影响 ,该研究将有助于寻求最优竞标策略。
There are many bidders in the electricity market, which not only “make the whole move faster” but also one or a few bidders can completely control the market behavior. Therefore, the market issue is actually a complicated system engineering problem. In this paper, we study the formation mechanism of market electricity price by studying the trading mechanism of PX (power exchange), set up the mathematical model of market electricity price, and deduce the formula that electric power company changes the bidding strategy’s influence on PX market electricity price. The simulation results of the data clearly show the impact of changing the bidding strategy of the power company on the PX electricity price and trading volume during the operation of the unregulated electricity market. This research will help to find the optimal bidding strategy.
