This paper determines and compares the cost of energy (COE) of various hybrid systems for several off-grid facilities in North and Far North regions of Cameroon by integrating renewable sources and/or storage with diesel generators. The estimated annual energy production by solar PV systems and wind turbines is also discussed. The aim is to study the application of a high penetration renewable ...

This paper presents a novel strategy, optimized by genetic algorithms, to control stand-alone hybrid renewable electrical systems with hydrogen storage. The strategy optimizes the control of the hybrid system minimizing the total cost throughout its lifetime. The optimized hybrid system can be composed of renewable sources (wind, PV and hydro), batteries, fuel cell, AC generator, and electrolyz...

This paper presents an autonomous hybrid generation system consisting of wind turbine generators (WTG), a diesel engine generator (DEG), fuel cell (FC), a battery energy storage system (BESS) and an aqua electrolyzer (AE). The generated hydrogen by an aqua electrolyzer is used as fuel for a fuel cell. The power system frequency deviates for the sudden changes in load and generation. The output ...

This paper describes modeling and simulation of a renewable energy based hybrid power system in the aspects of improving power quality, energy management and control, because optimal utilization of primary energy sources will increase the level of supply reliability. In order to meet sustained load demands during varying natural conditions, different renewable energy sources and converters are ...

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...

A methodology is developed for calculating the correct size of a photovoltaic (PV)-hybrid system and for optimizing its management. The power for the hybrid system comes from PV panels and an engine-generator – that is, a gasoline or diesel engine driving an electrical generator. The combined system is a stand-alone or autonomous system, in the sense that no third energy source is brought in to...

Renewable and non-conventional distributed energy resources (DERs), such as, wind, solar PV, micro-turbines, fuel cells, diesel generators etc. are gradually becoming more popular as energy efficient and low-emission energy sources. Demand-side management, along with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the...

-The paper presents the viability of domestic standalone Photovoltaic (PV) hybrid systems in Indian rural areas. The standalone supply system powered by single nonconventional sources such as solar, wind turbines or tidal face unpopularity due to the inconsistency and undependable variance in their source throughout the day/year. The above drawbacks can be addressed by combining minimum of two ...
