Performance evaluation of conventional demand response at building-group-level under different electricity pricings

摘要: Abstract One main objective of demand response is to release grid pressures imposed by building peak demands through changing end-user electric usage in electricity price changes. Conventional heating, ventilation and air-conditioning (HVAC) systems performed an uncoordinated way which merely focuses on individual-building-level economic benefits. However, its building-group-level performance, the real concern grid, has not been systematically evaluated. Thus, using operation data buildings, this study evaluates performance conventional at under common pricings. The evaluation results disclose major limitations due lack coordination. Under time use pricing, HVAC cannot effectively efficiently reduce building-group-level. dynamic can cause a new undesirable could be much larger than original one impose stress grid. Coordinating individual buildings solve these limitations. With improved building-group-level, simple coordinated examples have given demonstrate need coordination response. show significance better released if implemented.
