博弈论及其在电力市场中的应用(待续)

在电力市场中一个特别重要的研究课题是各个市场参与者如何在市场许可的条件下运用智慧进行合法竞争以获取最大的利益，以及市场监管组织怎样预测和判断不合理的竞争现象，这就需要运用博栾论的研究成果。文中拟对博奕论在电力市场中的应用做一简介。全文分为两部分：第1部分主要介绍博弈论的发展历史、分类，及其在各个领域中的应用，并通过举例简单介绍其基本的建模、求解过程及难点。第2部分主要介绍博弈论在电力市场中的应用，包括在发电公司售电决策、购电公司购电决策中的应用；输电成本分配和输电电价确定中的应用；以及判别分析操控市场行为中的应用。

GAME THEORY AND ITS APPLICATIONS IN POWER MARKETS

In power markets,a significant research area is how a market participant should bid strategically to obtain the maximum gain of itself without sacrificing constraints of the m arket and system operation constraints,and how the m arket administrator should estim ate and judge the unfair competitions.This issue requires applications of gam e theory.In this paper game theory and its applications in power m arkets are introduced.The paper is composed of two parts.The first part is to introduce the history and classification of gam e theory and its applications in various areas.Simple examples are presented to show how to build up a proper m ath m odel for a specific gaming problem and how to find its solution.The important concept of Nash equilibria and the difficulties in finding a feasible Nash equilibrium are also emphasized.The second part focuses on the applications of game theory in power markets,which include the bidding strategies of the generation com panies,the pricing of transm ission and wheeling and the rational allocation of the transmission cost,and the estimation and judgement of the unfair market power which may appear in the power market.
