Abstract
PV/Battery microgrids hold the most promising solution for providing electricity to remote areas. However, the power quality of these microgrids is vulnerable to nonlinear loads and power electronics components, often necessary to power certain systems such as the cereal grinding systems. These grinding systems consist of mills locally designed driven by induction motors. Given the constraints of microgrids and the structure of the cereal grinding system, a single-phase-to-three-phase Power Factor Corrector with two control strategies is proposed. The PFC control is used to control the power quality of the microgrid but also to regulate the DC-link voltage. The field oriented control strategy is used to improve the system efficiency. The performance of the power converter and control strategies are evaluated in simulation under Simulink environment. Results have verified the effectiveness of the proposed controls with a low current Total Harmonic Distortion, a near-unity power-factor and a significant efficiency improvement of cereals grinding system.
Highlights
In Senegal, more than 55% of the population lives in rural areas with an estimated electrification rate of 32%
To solve issues of food security and access to drinking water, significant progresses were noted on the development of water pumping system and grinding system using diesel engines
The use of diesel engines was an attractive alternative for traditional methods
Summary
In Senegal, more than 55% of the population lives in rural areas with an estimated electrification rate of 32%. To improve the living conditions of populations in rural areas, the electrification issue must be imperatively resolved. This is all the more true since, despite the significant policies efforts, food security and access to drinking water remain important issues in rural areas of the southern and central regions due to the lack of electricity. The use of diesel engines was an attractive alternative for traditional methods. The use of diesel was an attractive alternative to traditional methods
