Coordinated Control of Building’s Multi-units Air-conditioning system and Battery Energy Storage Systems for Improved Performance of FastADR Response

摘要

Fast Automated Demand Response (FastADR) is one of the expected measures to control electricity demand of consumers so that the balancing of electricity supply and demand in a short time horizon is improved. Due to their high power consumption in business buildings, Heating Ventilation and Air-conditioning (HVAC) loads are one of the promising resources for FastADR. However, due to their operational characteristics HVAC loads do not perfectly follow external control signals. In order to mitigate this problem, measures such as an improved algorithm for HVAC load units’ operation and the complementary use of Battery Energy Storage System (BESS) at an individual building level can be used. This paper proposes a coordinated control system of Multi-units HVAC system and BESS at an individual building level in order to fulfil FastADR signal requests while minimize the capacity of BESS required and maintain indoor room temperature comfort levels.
