Energy Storage System for Programmable Dispatch of Photovoltaic Generation

This paper proposes a structure to compensate for the intermittency of photovoltaic (PV) generation, allowing a programmable dispatch for small generators. The proposed system is based on the integration of a lithium-ion battery bank with a power inverter connected to the AC grid. This integration is made possible using a high voltage gain bidirectional DC-DC converter. With this, the system is able to provide a constant power flow to the grid. To validate the proposed system, real-time HIL (hardware-in-the-loop) simulation with real data of solar irradiance are used.
