Market-based Management of Distributed Generators in Competitive Power Systems

本研究的目的是研究一个基于市场的管理框架，其中分布式发电机的决策是通过买卖能源和服务的市场间接控制的。(1)被控对象模型：在被控对象为大型发电机和电网的情况下，在引入分布式发电机的电力系统的可靠性值与常规电力系统的可靠性值相同的情况下，建立了确定大型发电机最优组合的方法。(2)市场模型：建立了给定市场（现货市场、双边市场、储备市场）下分布式发电机组最优决策模型。(3)分布式发电机组在市场中的作用经济分析：从经济角度考察大型分布式发电机组对寡头垄断市场的影响。(4)环境价值买卖市场管理：利用多智能体理论和q -学习对可再生能源信用买卖市场进行建模，并进行了市场仿真。(5)可靠性（备用）买卖价值的市场管理：建立了故障发生时的两种能量补偿模型，探讨了在竞争电力系统中获取所需备用功率的理想途径。

The purpose of this research is to investigate a framework of a market-based management where decision-makings of distributed generators are controlled indirectly through markets for selling and buying energy and service. The obtained results through this research are summarized as follows :(1)Model of Controlled Object : In the controlled object which is composed of large-scale generators and electric power network, a method for determining the optimal mix of large-scaled generators was developed under the condition where the reliability of power system in which distributed generators were introduced has the same value as that of the conventional power system.(2)Model of Market : Models for obtaining a optimal decision-making of distributed generators for given markets such as spot market, bilateral market, reserve market was developed.(3)Economical Analysis on Roles of Distributed Generators in Market : How large distributed generators give impacts on oligopoly market was investigated economically.(4)Management by Market for Selling and Buying Value of Environment : Market for selling and buying renewable energy credit was modeled by multi-agent theory and Q-learning, and some simulations using the market were executed.(5)Management by Market for Selling and Buying Value of Reliability (reserve) : Two kinds of models for compensating the energy in the fault occurrence were modeled and a desirable way for procuring the required reserve power was investigated in the competitive power systems.
