A study on demand response effect of thermal storage air‐conditioning systems in consideration of electricity market prices

This paper evaluates the economic impact of the introduction of customer-owned Thermal Storage Air-conditioning (TSA) systems, in an electricity market, from the viewpoint of the load service entity (LSE). We perform simulations on the condition that several thousand customers install TSA systems and shift peak demand in an electricity market by one percent. Our numerical results indicate that the purchase cost of the LSE was reduced through load management of customers with TSA systems. The introduction of TSA systems also reduced the volatility of the market clearing price and reduced the whole-trade cost in an electricity market. © 2011 Wiley Periodicals, Inc.
