Now a day‟s electricity is most needed facility for the human being. All the conventional energy resources are depleting day by day. So we have to shift from conventional to non-conventional energy resources. In this the combination of two energy resources is takes place i.e. wind and solar energy. This process reviles the sustainable energy resources without damaging the nature. Renewable ener...

Wind-photovoltaic hybrid system (WPHS) utilization is becoming popular due to increasing energy costs and decreasing prices of turbines and photovoltaic (PV) panels. However, prior to construction of a renewable generation station, it is necessary to determine the optimum number of PV panels and wind turbines for minimal cost during continuity of generated energy to meet the desired consumption...

This study deals with system integration and power management of a stand-alone renewable energy (RE) hybrid system, which is in its final stage of construction in Lambton College (Sarnia, Ontario, Canada). The system consists of five main components: photovoltaic (PV), wind turbine, electrolyzer, hydrogen storage tanks and fuel cell. The model for each process component was developed and the hy...

Demand-side energy management systems (EMSs) are expected to be used as a method for further balancing the supply and demand of power systems with high levels of renewable energy generation, such as photovoltaic (PV) power. Energy demand and solar radiation must be predicted to realize the optimal operation scheduling of demand-side appliances by a home energy management system (HEMS), includin...

The economics and livelihoods impacts of stand-alone, small-scale (less than 2 kW) renewable energy technologies for rural electrification are assessed using a representative sample of 531 rural households in three provinces of Western China. Over 20 small wind, photovoltaic (PV) and wind–PV hybrid configurations were evaluated for their potential to meet local electricity needs. The assessment...

Photovoltaic (PV) power generation is one of the cleanest sources for producing renewable energy; however uptake on the Irish renewable energy market to date has been low. There is a lack of support for solar PV systems in Ireland; there is currently no solar PV energy feed-in-tariff as there are for other renewable energy systems in Ireland. Despite the current lack of support, the Government ...

The combination of the remote-area-diesel generators with a battery storage and renewable energy source such as photovoltaic (PV) can greatly overcome the problems of these generators. In this paper a PV/Diesel generator hybrid energy system is sized to meet the load for about 100% availability. Where, for a given load characteristic and a given diesel generator a methodology is developed to op...

We analyzed the cross-correlation of Photovoltaic (PV) output fluctuation for the actual PV output time series data in both the Tokyo area and the whole of Japan using the principal component analysis with the random matrix theory. Based on the obtained cross-correlation coefficients, the forecast error for PV output was estimated with/without considering the cross-correlations. Then operation ...

This paper studies the possibilities of decomposition of the current in three-phase, three-wire systems based on the classic p-q theory. Recently, the energy crisis in the world has led to the rise in use of renewable energy sources with the advancement in power electronics technology, the solar photovoltaic energy has been recognized as an important renewable energy resource because it is clea...

The increasing penetration of renewable sources with power-electronic interfaces in power systems is raising technical problems and the overall efficiency of photovoltaic systems can decrease dramatically. In this context, the optimal layout for the photovoltaic system is required. The most adequate strategy to connect the renewable system to the electrical power grid or to supply the end users...
