Demand and Storage Management in a Prosumer Nanogrid Based on Energy Forecasting

Abstract

Energy efficiency and consumers’ role in the energy system are among the strategic research topics in power systems these days. Smart grids (SG) and, specifically, microgrids, are key tools for these purposes. This paper presents a three-stage strategy for energy management in a prosumer nanogrid. Firstly, energy monitoring is performed and time-space compression is applied as a tool for forecasting energy resources and power quality (PQ) indices; secondly, demand is managed, taking advantage of smart appliances (SA) to reduce the electricity bill; finally, energy storage systems (ESS) are also managed to better match the forecasted generation of each prosumer. Results show how these strategies can be coordinated to contribute to energy management in the prosumer nanogrid. A simulation test is included, which proves how effectively the prosumers’ power converters track the power setpoints obtained from the proposed strategy.

Design of a Smart Nanogrid for Increasing Energy Efficiency of Buildings

“…However, more advanced control techniques have been reported that also engage controllable loads in combination with the generation and storage devices. Specifically, in [28] an energy management system (EMS) has been designed by considering the financial gain of the prosumer through three steps; namely energy monitoring, DSM through the available smart appliances, and management of the ESS in order to match the forecasted generation. The implementation of the proposed EMS results in improvement of the energy balance within the nanogrid.…”
