Experimental Investigation and Control of a Hybrid (PV-Wind) Energy Power System

Abstract

The most essential infrastructure of today’s modern civilization is the energy system. A new energy revolution is ongoing worldwide in understanding the affordability, reliability, and sustainability of energy supply. One of the major challenges and opportunities considered in this energy revolution is the integration of the energy system. The varying dynamics of renewable energy production and the environmental conditions between the different energy sources are the major reasons for this challenge. Wind and solar energies are considered the best renewable sources and the foremost substitute sources for power generation. These energies are playing a vital role as alternates of nuclear energy and fossil fuels. Electricity is generated through wind energy conversion systems and photovoltaic (PV) cells. These technologies are clean and environmentally friendlier than non-renewable energies. A hybrid PV-wind generation system is more effective and consistent than a single-source system because the solar system cannot work at night or in cloudy weather while the wind speed is variable. The current study proposes an experimental-based analysis. The hardware used is the Squirrel Cage Induction Generator (SCIG) and solar panels. A boost converter is added for Maximum Power Point Tracking (MPPT) at variable wind speed and available sunlight.

Optimized Wind Turbine Emulator based on an AC to DC Motor Generator Set

“…The sensed angular speed Ω fed of the IM and the wind profile speed were employed to obtain the maximum power using (8). Then, reference angular speed Ω opt was obtained according to (9).…”

“…Some are based on permanent magnet synchronous machines [3], DC, or induction motors to replace the mechanical part [4][5][6]. Many electrical machines have been considerted for the generator part, such as self-excited induction generators [7][8], permanent magnet synchronous generators [9][10], or DC generators [11]. The study of emulators focuses on several parameters such as the generator speed, pitch angle, maximum power, and torque [12].…”

Development of Renewable Energy Sources to Serve Agriculture in Vietnam: A Strategic Assessment using the SWOT Analysis

“…In bad weather conditions, renewable energy technologies, such as photovoltaics or wind turbine generators, will be used less often. Wind speed variations alter the power generated through wind turbines, whereas the power produced through photovoltaics is affected by deviations in solar radiation and varying temperatures [21]. Therefore, weather conditions affect the stability, reliability, and quality of the power supplied to agricultural production.…”

Application of An Adaptive Network-based Fuzzy Inference System to Control a Hybrid Solar and Wind Grid-Tie Inverter

“…The studied system configuration is introduced in Figure 1. It includes a 5kWp rooftop solar PV system and a 3kW wind turbine system connected to the power grid through a hybrid grid-tie inverter [9,14]. The mathematical models of the proposed system are described below.…”
