Design of an energy management system for microgrids applied to an isolated system incorporating solar thermal energies

Abstract:

This chapter presents an hourly energy management system (EMS). The hybrid renewable energy system (HRES) is composed of a hybrid ae-generator system (WT), solar photovoltaic (PV) panels, a diesel generator (DG) and a distributed collector system (DCS) as the primary energy source. The distributed collector system (DCS) consists of a eld of parabolic trough collectors that carry solar thermal energy to a power conversion unit to produce electricity, an energy storage system (ESS), the wind turbine, the PV panels and the distributed control system (DCS) are made to work at the maximum power point, while the battery acts as storage. The energy management system (EMS) uses intelligent rule-based controllers to meet the energy demanded by the load and maintain the state of charge (SOC) of the battery between certain target ranges. The controller implemented for this study is a fuzzy logic controller that mimics human understanding of various phenomena that may occur during microgrid operation. The simulation results show that the fuzzy logic-based control meets the objectives established for the energy management system (EMS) of the hybrid renewable energy system (HRES).
