This paper, presents a suitable control system to manage energy in distributed power generation system with a Battery Energy Storage Station and fuel cell. First, proper Dynamic Shape Modeling is prepared. Second, control system is proposed which is based on Classic Controller. This model is educated with Genetic Algorithm and particle swarm optimization. The proposed strategy is compared with Classic...
An optimization method is used for determining the electric power to be supplied at the different nodes of a microgrid with the aim of reducing generation costs, losses by electricity transmission, and greenhouse gas emissions, while simultaneously maintaining the energy quality at all points of supply. The optimization problem is complex due to the various restrictions inherent to the distributed...
This paper focuses on unit sizing of stand-alone hybrid energy systems using bees algorithm. With different combination of renewable sources, two types of hybrid energy systems are taken as test systems. Apart from the non-conventional sources like wind turbines, solar panels along with micro hydro plant, the systems have been optimized with fuel cell, converters, electrolyzers and hydrogen tanks...
In this paper a new methodology is proposed to evaluate the effect of energy storage systems on optimal size and total cost of an islanded micro-grid that consists of wind turbines, photovoltaic panels, fuel cells and the capacities of battery banks (as energy storage systems), interruptible and uninterruptible loads. When total of produced power in micro-grid can't satisfy demand, first interruptible...
Anticipated high penetration of stochastic energy flows throughout the stand-alone micro grids should be optimized by using hybrid stochastic-heuristic simulation methods. It is well treated, in this way, both the uncertainty caused by the renewable power production and the non-linearity of the objective function. In this paper, a hybrid simulation procedure is employed to the problem of sizing in...
In this paper a novel intelligent method is applied to the problem of sizing in a hybrid power system such that the demand of residential area is provided. The system consist of fuel cells, some wind units, an electrolyzer, a reformer, a compressor, an anaerobic reactor and a hydrogen tank. The system is assumed to be stand-alone and uses the municipal waste as an available energy resource. PSO algorithm...
