Proposal and Experimental Implementation of a Demand Dispatch System for IoT-ready Home Appliances

Abstract

Since solar power generation has increased rapidly, balancing function, especially in the form of increasing demand, is becoming needed. We propose technique of demand response in which an aggregator dispatches home appliances expected to be IoT-ready in the near future in order to consume the surplus deriving from over-generation of solar energy.

In this study, assuming that such an aggregator could be an energy retailer as well, this demand dispatch is provided to customers as an energy service and also offered to the power system operator as a balancing function. An experimental demand dispatch system is implemented, and challenges are pointed out such as an error between target demand value to be increased and actually dispatched demand value.
