Economic dispatch in an offshore island system with high wind power penetration

Generation cost of an island power systems typically exceed that of a large grid system. Therefore, most countries initiate their plans to develop renewable energy on remote offshore islands. However, the integration of a significant amount of renewable power in isolated systems requires careful consideration in order to ensure high reliability and security for the power system operation. To consider system economics and stability simultaneously, an optimal algorithm to determine the real-time economic dispatch (ED) is the first step. In several island power systems, the incremental fuel cost is non monotonicity so that several conventional economic dispatch methods could not be applied to those systems. This study discussed various ED methods and implemented mixed integer linear programming (MILP) to an actual island power system.
