500kWh outdoor energy storage unit for Chilean microgrid in rural areas

Where are Chile's battery energy storage facilities located?

Chile’s first battery energy storage projects were commissioned in 2009, and all but two of its 16 administrative regions have facilities in operation, under construction or in the planning stage. The greatest installed capacity is found in the northern regions of Antofagasta and Tarapacá, the country’s solar powerhouses.

What is a photovoltaic microgrid power supply system?

According to the analysis of the distribution of renewable energy in rural areas, a typical photovoltaic microgrid power supply system is established as shown in Fig. 1. The microgrid includes a photovoltaic power generation system, energy storage devices, rural industrial loads, rural agricultural loads and rural resident loads. Fig. 1.

What is the reliable power constraint of microgrid system?

The reliable power constraint of microgrid system can be expressed as, (15) k P ol ≥ P p where k represents the short-time allowable overload coefficient of the energy storage system, P P represents the maximum impact power when the important load is started in the microgrid system, P ol stands for short-time allowable overload power.

Can optimized photovoltaic and energy storage system improve microgrid utilization rate?

The results show that the optimized photovoltaic and energy storage system can effectively improve the photovoltaic utilization rate and economic of the microgrid system. The model can provide an effective method for the design of photovoltaic and energy storage configuration schemes for microgrids in rural areas. 1. Introduction
