Use of hybrid solar-wind energy generation for remote area electrification in South-Eastern Nigeria

Abstract

This paper presents simulated hybridized solar-wind generation as an alternative for rural dwellers that do not have access to a conventional grid connection. Solar and wind were used as the main sources of energy with battery storage. Each power source has a DC-DC converter to control the power flow. An axial flux permanent magnet generator, which is suitable for a location with a low wind speed, was driven by the wind turbine. By using this generator, the efficiency of the system increased since certain losses were removed. The perturbation and observation method of MPPT is used to achieve maximum power extraction from the solar panel. The hybrid system was modelled in Matlab/Simulink software. A squirrel cage induction motor was used as the electrical load to the system load. The results obtained for the proposed hybrid system indicates that it can be used as an isolated power supply. By doing so, it improves the standard of living and hence, increasing total number of citizens using energy in the country.

“…Another possible configuration is wind-solar-BS (Atia and Yamada, 2016;Ahadi et al, 2016;Nnadi et al, 2014). The complementary nature of wind and solar in this configuration reduces the storage requirements and improves system availability.…”

“…Its production covers a third of the world's energy consumption, which is mainly concentrated in thermal machines where combustion is on a large scale with the direct emission of millions of tons of CO2 causing high levels of pollution and global warming; and reduction of nature reserves [1].Renewable energy production techniques have evolved in terms of power and performance over the past decades. It has been used all over the world, especially in remote areas [2]. For economic reasons, the recent increase in oil prices obliges each country to choose the strategy of electric energy production, with an acceptable blow according to the possible wealth, and to exploit the sources of energy to the maximum.…”

“…In particular, the cost of photovoltaic panels is reduced, which encourages investors to take charge. In particular that the availability of two sources of wind and solar energy, this gives us a sufficient argument to implement a hybrid source technology sufficiently mastered and managed to take major steps in the field of various applications and energy consumption, whose optimization of these systems will surely lead to a better use of solar and wind energy, in order to ensure the optimization control and operation of these systems which will surely lead to a better use of solar-wind energy [2]. A comparison has been made for many hybrid system optimization techniques [12] witch have been reported that could be applied to achieve a technologically optimal hybrid renewable energy system [13][14][15][16].…”

“…This problem affects the optimum operating point called the MPP which is linked to two factors which are the temperature and the solar radiation and the variation of the load for the first and the second depends on the kinetic speed of the wind, and Beltz limits. Typically, in a variable speed wind power system, below rated wind speed, the electrical torque is controlled to drive the system at an optimum speed for maximum energy conversion [1,2]. In order to transfer the maximum energy supplied by the two wind-solar generators to the load, a MPPT is used.…”

Design and Comparison of Standalone Bladeless Wind Solar Hybrid System with the Conventional Standalone Wind Solar Hybrid System

“…So solar can be used for power generation but even it has disadvantage that it is not available at night times and no power generation. So, using of single renewable source at a time may not meet the load requirement and so by combining these sources [2,3] they can be effectively used which leads to hybrid system. Standalone Hybrid power generation system [4][5][6] produces electrical energy with the use of more than one source and if one is not available another source can be used +for running the load.…”
