Optimal design of an island microgrid with considering scheduling optimization
Stand-alone microgrid system consist of hybrid wind/PV/diesel/storage is one of the effective approaches to solve the problem for future island power supply while plan and design are one of the core technical systems of it. According to operation requirements of the island stand-alone microgrid and the characteristics of distributed power supply as well as the optimization demand of microgrid capacity, an optimized scheduling model for microgrid that consider the initial investment cost, maintenance and replacement cost, fuel cost, environmental management cost, and power shortage penalty cost is proposed in this paper. The constraint of the utilization rate of renewable energy, single and total loss of power supply probability (LPSP), single and total dumped energy proportion (DEP) are also under consideration. Through the establishment of the mixed integer linear programming model (MILP), the integrated modeling and solving of the stand-alone microgrid planning and optimization scheduling problem are realized. The effectiveness of the designed model is verified through the result of some island microgrid. Furthermore, the impact of the reliability constraint of the system power supply and the penalty factor of the dumped wind/PV energy is analyzed.
