Optimal Operation of Combined Heat and Power in Hierarchical Micro Grid
The micro grid is a small power system, which consists of several loads and distributed generators (DGs). The effects expected from the micro grid are the effect of decreasing of environmental load by the introduction of photovoltaics (PV) or fuel cell (FC) and the realization of efficient utilization of energy by the introduction of cogeneration system (CGS) such as gas engine (GE), etc. In this paper, in order to take full advantage of these effects, the authors propose a concept of Hierarchical Micro Grid (HMG) as one form of a micro grid. The feature is satisfying the demand-and-supply balance of both heat and electric power, by optimally controlling the demandand- supply balance of heat of each consumer and hierarchically controlling the demand-and-supply balance of electric power between each consumer. In this study, the optimal operation schedule of each power supply is determined using the particle swarm optimization (PSO) which is one of the optimization methods. In order to verify the validity of the determined optimal operation of HMG, the consumption of primary energy and the CO2 emission are evaluated by the case of the optimal operation of HMG, and the case of operation of conventional micro grid.
