Operation Management of Power Grid System with Renewable Energy Sources and Energy Storage System Integrations

Sudan is a large country because of the large territory and the distance between communities are simply too great, a full- scale power grid is almost impossible to realize. As a result, the construction of small Island power grids in remote areas has been developed. The country shows favorable conditions for the generation of electricity by renewable energies such as wind and solar. Nyala city has been chosen as a preferred wind farm location because the power supply by the existing diesel power plant is expensive due to high costs for fuel transport and the reliability of power supply is low due to uncertain fuel provision. This paper presents a formulation of security-constrained unit commitment (SCUC) with diesel generation and integration of wind power and solar photovoltaic with the compressed air energy storage system (CAES) for Nyala city power plant. The proposed system is formulated as a mixed-integer programming, which is solved in CPLEX 12.7.0. and the results show that the proposed model is suitable for renewable integrations into the power grid system with energy storage systems.
