A recent trend in the design of hybrid energy systems is the development of standardised systems, which can support a variety of applications. The performance of parallel hybrid energy systems can be improved through the application of advanced control methods implemented by a centralised system controller. Optimum resource allocation based on load demand and renewable resource forecast, promis...

The main objective of this work is to design an optimal—efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Four renewable energy power systems are presented in this paper to select the most optimum one of them. These suggested renewable energy systems a...

In this paper, the optimum design for renewable energy system powered an aquaculture pond was determined. Hybrid Optimization Model for Electric Renewable (HOMER) software program, which is developed by U.S National Renewable Energy Laboratory (NREL), is used for analyzing the feasibility of the stand alone and hybrid system in this study. HOMER program determines whether renewable energy resou...

Considerable efforts have been made to reduce the energy consumption of buildings due to the energy crisis, and, the Korean government has supported the use of renewable energy through various grants. Among the possible renewable energy sources, geothermal energy can be used regardless of the outside weather. Therefore, energy consumption can be reduced considerably in summer and winter. Despit...

The rapidly growing server energy expenditure and the warning of climate change have forced the IT industry to look at datacenters powered by renewable energy. Existing proposals on this issue yield sub-optimal performance as they typically assume certain specific type of renewable energy sources and overlook the benefits of cross-source coordination. This paper takes the first step toward expl...

This paper analyzes utilization of renewable energy systems and efficient building envelopes in the semi-arid climate. The proposed model evaluates renewable energy systems solutions as well as economic- and energy-efficient construction materials for the net zero-energy buildings (NZEB) in semi-arid climates. The objective of this paper is to optimize total energy cost and environmental impact...

In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar  systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , p...

Renewable energy types such as solar, wind or geothermal energy have been increasingly considered by different countries over the last few years in order to diversify power sources, reduce dependence on one single of energy, and achieve sustainable energy. On the other hand, rising prices of fossil fuels and the fact that they are finite, environmental pollution and evolution of the related tec...

The article presented here utilizes the particle swarm optimization (PSO) and water cycle algorithm (WCA) based dynamic voltage restorer (DVR) to augment low ride through (LVRT) performance of a hybrid renewable energy system (HRES). Moreover, FACT equipment like is deployed boost quick responsiveness compensation good transient HRES. Due numerous disturbances brought on by WECS' nonlinearity, ...
