Abstract
Renewable energy resources are generally unstable and affect the performance of electricity grids when they are fully connected. A distributed energy supply network system is expected to overcome the above problem. Such a system consists of a network system in which electricity and heat can be transferred between dispersion generators and the renewable energy resources and can supply stable energy to an urban district. We have constructed a self-organization model for the formation of dispersion energy network. We demonstrated that the following 2 functions can be realized by the multi-agent model which has rules for introduction of energy facilities (fuel cell cogeneration system (CGS), heat pump system (HP), photovoltaic (PV) systems and conventional system). 1) Energy exchange was achieved between neighbor houses and surplus energy was consumed in urban district. 2) “Energy colony” is formed for self-organizing.
Our simulation results indicated that stable energy exchange was possible when “Energy colony” was formed in the district. It is considered that it is possible to construct self-organization energy network in a real dynamic urban energy environment by applying the facility replacement rules determined in this study.
