A Novel Algorithm for Optimal Transfer of Power in Hybrid Power Generation Units

Abstract

Smart micro-grid is a new kind of power grid. In smart micro grid to produce electricity
various renewable energy resources may be used and store them in power storage device.
However, power losses are a major problem in power exchange between the macro-station
and micro-grid. In this paper, a greedy coalition formation algorithm allows the macrostation to mutually coordinate power exchange between the macro-station and micro-grid,
with power storage device. This algorithm optimizes the total power losses across the entire
micro-grid, including the power loss due to charging and discharging power storage device,
generation and power exchange. This algorithm creates a set of micro-grid pairs, giving
priority to micro-grid pairs with the higher power losses reduction per exchange power unit.
Through computer simulations, the proposed algorithm is demonstrated that optimally
reduces the average power loss in entire micro-grid.
