Operational Risk Assessment based Energy Management in Microgrid using PV Generation

Microgrids are small distribution system interconnected to distributed energy sources and battery energy system to meet its local demand independently or in coordination with the main grid. This characteristic of microgrid can be used as an alternative to reliance on electricity generation and distribution when grid remains inoperable due to technical glitches or catastrophic severities. To exploit this advantage of microgrid, this paper proposes an operational risk assessment based energy management of microgrid. The risk assessment has been achieved by appraising the microgrid value in the presence and absence of grid energy. After assessing the microgrid value, energy management of the system using PV and battery energy storage by linear programming optimization technique has been performed to proliferation microgrid antifragilie nature. This further led to the increase in system reliability and robustness. The efficacy of the proposed work has been demonstrated using a small network model consisting of utility grid, Photovoltaic (PV) array, batteries and variable load whose energy management was optimized using linear programming technique to obtain a robust and reliable system when operated with the grid or in isolation.
