This paper presents the evaluation performance of 15kWp hybrid power system based on AC Coupled PV Diesel Hybrid power system in Malaysia. The system consists of 15 kWp of Photovoltaic (PV) array, 11.4 kW of inverter, 36000 AH of total battery capacity, 10kW bi-directional (BD) inverter and 12 kVA of diesel generator (DG). The system provides electricity to one of remote schools in Sabah, East Malaysia...
Energy efficiencies of different hybrid systems are investigated in an urban bus cycle. A diesel bus is converted into a multihybrid bus also capable of operating in a direct diesel drive. The target is to investigate which kind of a hybrid system provides the lowest fuel consumption in different operating conditions.
Wind and solar are considered as if the most beautiful form of non renewable source of energy for harvesting the electricity to meet the global energy demand. Off grid hybrid systems are more useful as compared to grid connected system for supplying the rural areas and grid isolated system. Both hybrid and conventional system can together increase the stability of the system and hence economical in...
This paper proposes a methodology for configuring hybrid solar-wind-diesel-energy systems at minimum cost and minimum dumped load. An iterative optimisation technique has been developed to calculate, the optimum system configuration to achieve minimum hours of loss of power supply and minimum annualized cost of system (ACS). The decision variables included in the optimization process are the number...
In the paper resources save control of hybrid power system is presented. Conditions for minimizing fuel consumption and maximize profit are obtained. Method for reducing torque ripple of the synchronous generator, which reduces energy loss and increase stability are proposed.
To operate as a stand-alone power system during grid power outages or peak price periods, local energy systems are equipped with storage devices and different distributed generations (DGs) such as diesel generators and renewable energy sources (RES). Power management of these hybrid systems will be challenging due to the intermittent and uncontrollable nature of many types of RES, load variations...
Decentralized generation (DG) systems are developed nowadays, as one of the possible means of addressing electricity and environmental challenges; they also offer social and economic benefits. DGs are suitable both for stand-alone and grid-tied applications. When operated in stand-alone, they could provide electricity for non-grid connected homes. However, in a grid-tied mode, they could supply power...
In Japan, Feed in Tariff has started since July in 2012. Moreover only solar power is not attractive energy, a wind turbine generator is attractive energy from the point of view to reduce double carbon oxide emission. However, to connect the wind turbine generator system to the grid, the independent power producer (IPP) must compensate the power disturbance caused of the wind turbine. Thus, a power...
Validation of hybrid systems is complex due to interactions of both continuous and discrete dynamics. Simulation is the most widely used form of system validation using a combination of random and constrained-random tests. Directed tests are promising since orders-of-magnitude less number of directed tests can achieve the same coverage goal compared to random tests. While directed test generation...
This paper deals with a new autonomous wind-hydro hybrid generation system consists of one squirrel-cage induction generator (SCIG) driven by a variable-speed wind turbine and another SCIG driven by a constant-power hydro turbine feeding three-phase four-wire medium loads. The proposed system consists of two back-to-back-connected pulse width modulation controlled insulated-gate-bipolar-transistor...

This paper enumerates the simulation of hybrid Wind-Photovoltaic stand alone system used for remote applications as standalone systems. The method of investigation concerns with the definition of the system topology, interconnection of the various sources with maximum energy transfer, and optimum control. The optimal transfer of power from the sources are based on power demand, voltage and current...
Renewable energy is gaining its importance widely on because of continuous degrading of conventional energy resources. Due to the intermittent availability of renewable energy sources which makes the system variable in nature, the involvement of power electronic components gain its importance. This paper investigates the various methods practiced in power electronic interfaces to tap energy from hybrid...
Driven by global warming suppression and depletion of fossil fuel resource, micro-grid (MG) especially the one with renewable sources such as solar photovoltaic (PV) and wind generations (WG) are getting attention in power systems. Nevertheless, due to the unpredictability and fluctuation of the energy generated by renewable energy resources, it is hard to adapt to the change of the consumers' electricity...
Due to environmental conditions and the particular pattern of economic development, masses from all across the world have turned towards different types of energy sources for meeting their energy demands. But the lack of integration in between these sources is an important factor to be taken into consideration. In this study the incorporation of different energy sources on a single node is discussed...
Reducing the power consumption of base transceiver stations (BTSs) in mobile communications networks is typically achieved through energy saving techniques, where they can also be combined with local power generators to create a hybrid power system (HPS). Such a system has reduced power consumption and operational cost, without taking the advantage of real-time energy management. In this paper, we...
