The hybrid power system consisting of new energy inverters and diesel generators has become a typical case of independent power systems in remote areas. Aiming at the problem of generator overload caused by sudden load applying in such systems, this paper proposes a novel emergency control strategy which increases the inverter output power according to the changing rate of system frequency. This control...
This paper presents a study of the modelling and intelligent control of a stand-alone hybrid energy system based on solar-wind-diesel with battery. In this study as the proposed system operate in a standalone mode the power quality is expected to decrease by the fluctuations from each of the voltage and frequency with varying loads and each of the two renewable sources which have depended on the wind...
In this paper, frequency control performance in a PV-diesel hybrid system is improved by using an energy storage system (ESS) with a virtual inertia controller. Simulation results show that the proposed method is feasible to reduce the frequency deviations and delivers maximum power compared to a fuzzy logic controller based method.
Due to the uncertainties associated with wind profiles, the load side voltage and frequency control of a wind dominated Remote Area Power Supply (RAPS) system is a challenging task. The performance of such a wind dominated hybrid RAPS system consisting of a diesel generator, fuel cell system, dump load and mains load is investigated in this paper. Integrating a fuel cell into the RAPS system enables...
This paper presents voltage and frequency stabilisation methods of a hybrid wind-diesel power system. A technique for power sharing between a wind energy conversion system and a diesel generator system is also addressed during the wind-diesel hybrid operation. The output voltage and frequency of the wind energy conversion system is controlled by a load side converter. The voltage and frequency of...
