In this paper, optimal sizing of Distributed Energy Resources (DERs) in Microgrid (MG) is proposed. MG includes photovoltaic (PV)/wind hybrid system with storage energy system that contains electrolyzer, hydrogen tank, fuel cell and battery. Wind power uncertainty is proposed and reliability index is considered as a constraint. Particles Swarm Optimization (PSO) Algorithm is used to obtain global...
Preventive Maintenance Scheduling of generating units is an important requirement in a power system planning. The maintenance of the various equipments in a power System, especially the maintenance of generators is directly related to the overall reliability of the power system. However, the Maintenance Scheduling (MS) problem is a constrained optimization problem. The objective function of this problem...
In this paper, the placement of sectionalizers, as well as, a cross-connection is optimally determined so that the objective function is minimized. The objective function employed in this paper consists of two main parts, the switch cost and the reliability cost. The switch cost is composed of the cost of sectionalizers and cross-connection and the reliability cost is assumed to be proportional to...
The utilization of renewable energy sources in electric power systems is increasing quickly because of public apprehensions for unpleasant environmental impacts and increase in the energy costs involved with the use of conventional energy sources. Despite the application of these energy sources can considerably diminish the system fuel costs, they can also have significant influence on the system...
