Developing of Stand-Alone Power System Simulation Model

International Review of Automatic Control (IREACO), 2014
In last two decades, the importance of stand-alone power systems has increased. No matter, if the system is a small mobile application like a smart phone or a large stand-alone house system, a simple simulation can be used for power flow control proposal.

Controlling a stand-alone power system

International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2006. SPEEDAM 2006., 2006
This paper deals with a hybrid power system based on renewable energy sources, working in stand-alone mode. It consists of a micro-hydro plant including a synchronous generator and a wind turbine with an induction generator. A frequency controller, based on dump load and common voltage regulator for the two generators, ensures the system's power ...

Modelling of a residential solar stand-alone power system

2010 1st International Nuclear & Renewable Energy Conference (INREC), 2010
Modelling of residential solar powered stand-alone power system comprising photovoltaic (PV) arrays, and a secondary battery is presented. Besides, an economic study is performed to determine the cost of electricity (COE) produced from this system so as to determine its competitiveness with the conventional sources of electricity.

Stand-alone power system with synchronous and asynchronous generators

2008 11th International Conference on Optimization of Electrical and Electronic Equipment, 2008
In the Synchronous Generator (SG)+Asynchronous Generator (AG)+Load (L) system there are, for certain load values, one or three working points. In this paper, we present the correct assessment of the working point with a view to building a mathematical model of generators valid both in stationary and transitory regimes.

Design and control of a stand-alone hybrid power system

International Journal of Hydrogen Energy, 2016
Abstract This work presents a control of stand-alone hybrid system including photovoltaic (PV), wind turbine, fuel cell (PEMFC), storage systems and a dump load (in our case, an electrolyzer). All these sources are connected by a continuous bus to three phase load through a DC–AC converter.

Load control of a wind-hydrogen stand-alone power system.

International Journal of Hydrogen Energy, 2006
A new generation of load controllers enable stand-alone power systems (SAPS) to use one or many standard (grid connected) wind turbines. The controllers use fuzzy logic software algorithms. The strategy is to use the control loads to balance the flow of active power in the system and hence control system frequency.

Dynamics and stability of a wind stand-alone power system

Energy Conversion and Management, 1993
Abstract A simulation and digital computer model of a wind stand-alone power generation system, including wind turbine generator pitch control and a Superconducting Magnetic Energy Storage (SMES) unit, is developed for dynamic and stability evaluation. The effect of introducing the SMES unit for improvement of stability and system dynamic response is

NiCo-Metal-Organic Framework and Porous Carbon Interlayer Based Supercapacitors Integrated with a Solar Cell for a Stand-alone Power Supply System.

ACS Applied Materials and Interfaces, 2020
Nickel cobalt-metal-organic framework (NiCo-MOF), with a semi-hollow spherical morphology composed of rhombic dodecahedron nanostructures were synthesized by using a scalable and facile wet chemical route. Such a structure en-dowed the material with open
