Dynamic economic dispatch of hybrid microgrid with energy storage using quadratic programming

摘要

Electrical power demand increases rapidly due to the development of technology. In the contrary, the availability of non-renewable energy sources surely decreases. This problem will impact on the national energy security. To meet the need of a large electric power, it is required to develop a large area small scales of distributed generations. Distributed generations utilize renewable energy sources, such as PV, in order to minimize the use of non-renewable energy sources. To maximize the utilization of renewable resources, it is necessary to apply energy storage. This storage is needed to store excess energy generated by renewable energy based power plants. With the distributed generations and energy storage which are connected to the main grid through microgrid, it is important to optimize the operation of the power system in order to meet daily load. In this paper, the optimization problem is formulated as Dynamic Economic Dispatch which is applied on hybrid microgrid with energy storage. The problem is solved using Matlab-based quadratic programming.
