This paper presents automatic reactive power control of the isolated wind-diesel hybrid power systems. The synchronous generator (SG) is used for power generation from diesel and the induction generator (IG) is used for electric power generation from wind turbine. To minimize the gap between reactive power generation and demand, the variable sources of reactive power is used such as static sync...

Promoting the development of green technologies and replacing fossil fuel vehicles with electric ones can abate environmental anxieties issues associated energy supply security. The increasing demand for requires an upgrade expansion available charging infrastructure to accommodate fast public adoption this type transportation. Ethiopia set a pro-electric cars policy made them excise-free even ...

Different configurations of on/off-grid-connected hybrid renewable energy systems (HRESs) are analyzed and compared in the present research study for optimal decision making Sub-Saharan Africa, facing problems electricity deficit. A multi-criteria analysis is performed this purpose using MATLAB software simulation. The obtained results show that levelized cost (LCOE) corresponding to 0% power s...

Abstract:This paper presents the planning of an optimal Energy Management System (EMS) supported by a fuzzy logic Controller (FLC) for a residential grid-connected micro grid with hybrid renewable generation (Wind & Photo Voltaic) and storage system. Modelling hybrid system includes Renewable Energy Sources given at intermittent supply conditions and dynamic energy demand, and to make conceptua...

This paper presents a standalone hybrid power generation system based on low speed wind energy conversion system (WECS) using a variable speed permanent magnet synchronous generator (PMSG) with battery storage and diesel generator (DG). Different types of power management strategies are presents for minimal use of DG. For each PMS, mathematical model is developed based on the power balance (bet...

The considerable expansion of telecommunications infrastructure in non-electrified areas has led to massive consumption non-renewable energy sources by diesel generators. promotion renewable technologies as an alternative these generators is until now confronted with the problems Capital Expenditures and system reliability. hybridization fossil fuels energies would make it possible find a bette...

The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...

A potential solution for stand-alone power generation is to use a hybrid energy system in parallel with some hydrogen energy storage. In this paper, a pre-feasibility study of using hybrid energy systems with hydrogen as an energy carrier for applications in Newfoundland, Canada is explained. Various renewable and non-renewable energy sources, energy storage methods and their applicability in t...

Hybrid renewable power systems integrate two or more sources of energy, one of which is renewable, optionally a storage system and typically work in stand-alone mode. They are being considered more and more and we should increment their usage taking advantage of their positive benefits: free of charge resource availability, CO2 emissions reductions and subsidies. Dealing with their inconvenienc...
