电力公司改变竞标策略对PX市场的影响

STUDY ON DEREGULATED POWER MARKET UNDER ENERGY SUPPLYCOMPANIES CHANGING BID STRATEGY

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。

Problems in deregulated power market are complex system engineering problem because any bidder can make themarket change but no one can control the market completely. This paper presents how MCP is determined by PX and howmany MCQ is changed under energy supply companies changing bid strategy. This research work is based on analysis onmechanisms of deregulated power market. A spectrum of formulas for calculating MCP and its change under energy supplycompanies changing their strategy are educed in the paper. Number testing results based on the formulas show that theformulas can describe the changes under energy supply companies changing their strategy in deregulated power market. Theresearch work is useful to find the optimized bid strategy in the future.This project is supported by National Outstanding Young investigator (No. 6970025).
