Price-Based Demand Side Management (DSM) Coupled with Cold Thermal Energy Storage (TES) and Solar PV for Peak-Load Reduction
Abstract
Peak electricity demand has become a global concern. It causes grid transmission constraints and congestion, and also increases the cost of electricity for all users, specifically industrial consumers with high peak demands. Time-of-use demand side management coupled with thermal energy storage and off-grid solar PV can be an alternative to increase the flexibility and security of the whole energy system. The aim of the current paper is to study the potential of implementing time-of-use demand side management coupled with thermal energy storage and solar PV technologies using optimization techniques for shifting electricity peak loads of cooling processes in an industrial unit. It was found that considerable reductions can be achieved in electricity power demands in different tariff periods using optimization-based demand side management (DSM) together with thermal energy storage and off-grid solar PV. In addition, it was seen that coupling cold thermal energy storage and solar photovoltaic technologies is more energy-beneficial than using them separately.
