Optimal fuel consumption planning and energy management strategy for a hybrid energy system with pumped storage

Abstract

Energy management system is very critical for solving the energy problem in remote areas, especially autonomous systems that uses diesel generators. The fuel cost increases due to transport over long distances makes it unsustainable system. for that an optimal sizing of the hybrid microgrid energy system (HMGES) with an energy management control (EMC) strategy was proposed in this work for an isolated site in southern Algeria, which consisting of photovoltaic (PV) source, diesel generator (DG), with a power hydroelectric storage (PHS) system in order to increase the reliability. The HMGES based on renewable energy is profitable for supplying the domestics and agricultural demand. This work evaluates three different standalone systems that used to guarantee the supply of energy for the isolated Saharan zone. The HMGES with EMC system not only decrease the harmful CO2 emission due to the less consumption of fuel, but also reduce the system cost comparison with the (DG and PV/DG) standalone systems, which are the objectives function of this study.
