価格型デマンドレスポンスを通したマイクログリッドの経済性分析

抄録

In this paper, we developed Unit Commitment model based on IEEJ EAST 10 Machine system model parameters, and constructed the Day-ahead market and Hour-ahead market. We analyzed the impact of PV penetration on both of Utility side and Microgrid side by the optimization of scheduling of utility side and Microgrid side respectively. We analyzed the impact of PV penetration on scheduling variation of pump generator and thermal power generator for utility, impact on variation of marginal energy market price, and analyzed the impact of variation of marginal energy market price on microgrid scheduling. Moreover, by the price-demand mode, Through Day-ahead market and Hour-ahead market, we analyzed the interaction effect of scheduling result for utility and microgrid each other. And last, we calculated and evaluated the fuel cost for both utility and microgrid in case of with market and without market respectively, and concluded that scheduling result for both of utility side and microgrid have been improved, the win-win result that total cost is low than without microgrid response has been verified.
