Stability Analysis and Optimal Energy Management of a Stand-Alone Hybrid Micro-Grid

This paper presents the analysis of different spinning reserve calculation and allocation methods applied to an islanded hybrid power plant supplying the city of Garowe, in the North of Somalia. The preliminary analysis of the partially stochastic power flows, related to renewable energy system generators and load demand, allows to set minimum requirements to ensure the grid stability. Three criteria for the calculation of the spinning reserve and for its allocation on the generators involved in primary and secondary frequency regulation are here proposed and analyzed.
