Abstract

Abstract In several countries around the world, the transition from fossil fuels to renewable energies is considered an inevitable trend for the reduction of greenhouse gas emissions and the protection of the environment. It also helps to minimize dependence on fossil fuels which are exhausted over time. In Cameroon, the use of renewable energies appears as an alternative for commercial companies which depend enormously on the public sector which is the only supplier of electricity thanks to hydroelectric dams. Installing solar power systems and wind power systems can help businesses and industrial facilities directly use electricity generated from clean energy sources. Moreover, the need to reduce electricity costs and to move toward solutions that improve the environment from being polluted is felt. In this article, the results of an optimization study for a cement plant in Garoua Province, Cameroon, show that the hybrid wind and solar grid-tied energy systems in Scenario 1 are considered more efficient; on the environmental, economic and technical level than the solar energy systems connected to the electrical grid in scenario 2. The robustness and feasibility of this system thanks to the Homer Pro software and the optimization by particle swarm shows a reduction in the cost of the installation as well as a contribution to the protection of the environment. The optimal configuration of the hybrid power system connected to the grid includes wind energy with a capacity of 300 kW and solar energy with a capacity of 1500 kW, this system has a net present cost (NPC) of 5,596,978 USD, the cost of energy (COE) of 0.0847 USD/kWh, the investment cost of 1,140,000 USD and the operating cost of 384,877 USD.
