Microgrid (MG) with battery energy storage system (BESS) is the best for distribution system automation and hosting renewable energies. The proliferation of plug-in hybrid electric vehicles (PHEV) in distribution networks without energy management (EM) puts additional pressure on the utility and creates challenges for MG.
As shown in Fig. 1, the CS is composed of five parts: solar photovoltaic panels, wind turbines, energy distribution center (EDC), electric vehicles, and energy storage systems (ESS) this work, a scheduling period is 24 hours, and it is divided into T (48) timeslots, each of which is τ (0.5h). 06:00 am is the start of the scheduling period, …
Energy management plays a fundamental role in ensuring the optimal operation of a microgrid (MG). Since MGs rely heavily on renewable energy sources, having batteries provides a reliable backup. Equalization is important when using batteries in an MG, ensuring their health and prolonging their lifetime.
When the ESS price drops below 77 $/kWh, the last three cost curves are lower than the profit region. And the PV-ESS-based EV charging microgrid project is more likely to be profitable. This means that the PV-ESS-based EV charging MG project is still cost-effective even when the PV price is high, and the utilization rate of charging piles is …
Figures 6 and 7 show the hourly operating cost and energy storage status of the building microgrid under sunny conditions. It can be seen that due to the existence of the contracted electricity price, when the photovoltaic power generation is greater than the energy consumption of the building itself, the electricity is directly transmitted to the charging …
