Microgrid Configuration and Operation: BESS and H-PVW

Micro Grids

Micro grids with a high penetration of Renewable Energy Sources (RES) find application in two different sectors, both fast developing :

Rural electrification and Smart Microgrids (SMG).

Smart Microgrids (SMG) are the best way to integrate large share of Distributed Generation (DG) in the electrical public network.

Rural electrification has the purpose to provide electricity to remote villages exploiting the locally available RES, as much as possible.

These micro grid applications have different objectives and characteristics but they share some common technical problems due to the use of RES. The RES have an intermittent, aleatory, not programmable nature, which makes it difficult to provide a continuous power supply to isolated loads and to assure the energy dispatch of RES in the public distribution networks.

The introduction of powerful Battery Energy Storage Systems (BESS) LiFePO4 in the micro grids allows to balance the variability of RES and to transform the micro grids in fully controllable power production plants.

Micro Grids Operation Modes

By definition the micro grid is a small power system composed of one or more Distributed Generation units (DG), that can be operated independently from the public electricity system.

There are micro grids always separated from the bulk power system, which operate in “islanded mode” full time and micro grids that are configured to switch between “islanded” and “not islanded” modes of operation, dependent on the state of the main grid.
