Electricity load reduction in hybrid power systems using power pinch analysis

Abstract

Energy savings in an electrical system can be achieved through the use of energy-efficient appliances to minimise electricity consumption. This work applies the Power Pinch Analysis (PoPA) to guide electricity load reduction at the demand side of a HPS. The reduction in electricity load as well as cost can be determined from the power rating and operating hours of appliances in a HPS. Four new heuristics for load reduction have been proposed in this work. The results show that systematic efficiency improvement of the appliances has successfully reduced the total electricity consumption and cost.
