风-光-储混合电力系统的博弈论规划模型与分析

A Game Theory Based Planning Model and Analysis for Hybrid Power System with Wind Generators-Photovoltaic Panels-Storage Batteries

综合分析由风力发电、光伏发电和储能电池组成的混合电力系统的技术经济特性,提出一类基于博弈论的混合电力系统规划模型。该模型以风力发电、光伏发电和储能电池的投资者作为博弈参与者,选取发电/储能容量作为参与者的策略,其收益计及发电/储能电池的全寿命周期费用、售电收入、系统供电可靠性等因素。根据博弈模型中可能的联盟关系,提出了5种非合作/合作博弈规划模式,进一步论证了Nash均衡的存在性,并求得各博弈规划模式下的Nash均衡策略,即风—光—储混合电力系统容量优化配置方案。分析表明4种合作联盟博弈下的总收益均高于完全竞争的非合作博弈,且合作博弈下的联盟价值均大于0,其中风—光合作博弈是资源综合利用的最佳模式。

A planning model for the grid-connected hybrid power system based on the game theory is proposed through analysis of the characteristics of the wind power,photovoltaic generation and storage batteries in power industries.The players in the game model,i.e.wind power,photovoltaic generation and storage battery,maximize their own profits by choosing their capacities individually,taking into account the life cycle cost,the system reliability and the environment profits,etc.This paper discusses five different game scenarios,one non-cooperative game and four cooperative games,and illustrates the existence of their equilibriums.The analysis of the corresponding equilibriums indicates that the coalition values are all positive,and the payoffs of all the four cooperative games are larger than that of the non-cooperative game.It is also shown that the cooperation of wind power and photovoltaic generation is the best way to realize the reliable and cost effective generation.
