Market-based Management of Distributed Generators in Competitive Power Systems

这项研究的目的是研究一种基于市场的管理框架，其中分布式发电机组的决策通过出售和购买能源和服务的市场间接控制。(1)被控对象模型：在引入分布式发电机组的电力系统可靠性与常规电力系统可靠性相同的条件下，建立了由大型发电机组和电网组成的被控对象下大型发电机组最优组合的确定方法。(2)市场模型：在现货市场、双边市场、电力市场等给定市场条件下，确定分布式发电机组最优决策的模型。(3)分布式电源在市场中作用的经济分析：对大型分布式电源对寡头垄断市场的影响进行了经济分析。(4)利用多智能体理论和Q-学习方法建立了环境买卖价值市场模型，并利用该市场进行了仿真。(5)可靠性(备用)的市场销售和购买价值管理：建立了两种故障情况下的电能补偿模型，研究了在竞争性电力系统中获得所需备用电量的理想方式。

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.
