Thermal-Electric Modeling: A New Approach for Evaluating the Impact of Conservation Voltage Reduction on Cooling Equipment

It has been suggested in the literature that by reducing incoming voltage at a distribution feeder head or supply side of buildings, significant electricity savings can be achieved. This technique is called Conservation Voltage Reduction (CVR). Data-based analysis with and without CVR primarily used to support such assertions, which does not explain physics behind reduction energy consumption CVR. paper presents new approach for evaluating impact on cooling equipment. In this approach, thermal-electric model process developed MATLAB’s SIMSCAPE toolbox includes an accurate compressor coupled induction motor whose varied simulate Simulations performed using show Coefficient Performance (COP) equipment improves voltage. However, lost windings may nullify improvement COP render programs ineffective if range speed change small over allowable change. The simulation results increase 4% 90% rated compared consumed variable frequency drives-based appropriately controlled, it possible reduce their net keeping ratio constant showed 2.5% Thermal-electric modeling building is, therefore, vital accurately benefits as smart, power electronics-based end-use globally adopted.
