The paper is to propose a multi-input power converter (MIPC) for hybrid photovoltaic (PV) array, wind turbine (WT), fuel cell (FC) and battery storage (BT) connected AC grid network. The aim is to simplify the power system and reduce the cost. The proposed MIPC consists of a dc-dc converter and a dc-ac inverter. The output power characteristics of the PV array, WT and FC are introduced. The perturbation...
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...
This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system. The paper focuses on the combination of solar cell (SC), wind turbine (WT), fuel cell (FC) and ultra-capacitor (UC) systems for power generation. As the wind turbine output power varies with the wind speed and the solar cell output power varies with both the ambient temperature and radiation,...
This paper describes dynamic modeling and simulation results of a renewable energy based hybrid power system. In order to meet sustained load demands during varying natural conditions, different renewable energy sources need to be integrated with each other. The paper focuses on the combination of solar cell (SC), wind turbine (WT), fuel cell (FC) and ultra- capacitor (UC) systems for power generation...
We investigated a small isolated hybrid power system that used a parallel combination of dispatchable and nondispatchable power generation sources. The nondispatchable generation came from a nature-dependent wind turbine, and the dispatchable generations were a fuel cell and a diesel generator. On the load side, the nondispatchable portion was the village load, and the dispatchable portion was the...
