Research on solar radiation potential as a source of renewable energy in the Motru area

Abstract

The continuous development of the human society is in a close correlation with the increased consumption of electricity. In the past few years, the thirst for electricity at a global level, has led both to higher levels of pollution and the depletion of fossil fuels. For this reason, the issue of energy efficiency is a priority of energy strategy at national and EU level. In this context, a solution to the above problems is to increase the rate of production of electricity from renewable energy sources. Thus, the paper presents a study of solar radiation as a source of renewable energy, modelling and simulation of photovoltaic systems and validation of data numerical simulations data with the measured data in the Motru area.

Study of the possibilities to achieve an energy mix in areas affected by restructuring of lignite exploitation

“…The municipality of Motru is located in the south-western part of Gorj County in Romania, at the dividing line between Mehedinti County and Gorj County. The municipality is located on route DN 67A, 44 km from Targu-Jiu and 42 km from Drobeta Turnu Severin [3].…”

“…For simulation, in MATLAB -Simulink [7,8], model from Figure 7 was designed, where all particular parameters of the area were implemented, and components of each electricity generation element were exemplified and analysed as follows: for solar energy (8 MW photovoltaic plant), the modelling being presented in Nan, Grecea et al Article [3], for wind energy (4.5 MW wind farm), the modelling being presented in Sultan, Nan et al article [4], hydropower (10 MW micro hydropower plant using two 2 Francis turbines of 5 MW each), the modelling being presented in Amevi Acakpovi et al article and article by E. Donaisky [9,10]. Components of model for simulation of energy production installation used are given below: wind energy, Figure 8; solar energy, Figure 9; micro hydropower plant, Figure 10 and thermal power plant, Figure 11.…”

“…Analysis of the possibilities to achieving the proposed mix is based on the studies presented by M.S. Nan [3] and A. Sultan [4] (through the environmental data connected with help of meteorological station belonging to University of Petrosani) and taking into account major impact of social protection due to the restructuring of mining activities in analysed area. Thus, in the current study, it is proposed to include coal-based energy to reduce social and economic impact of the population, and the transition to clean energy to be made gradually while respecting the commitments made mix.…”

Use of hydrogen as a source of clean energy

“…Renewable energy sources are highly valued at the moment and their efficiency has been recognized worldwide. To promote renewable energy sources, many states have developed and implemented policies and strategies that facilitate access to these sources in the electricity system and support investment in this area [1].…”
