Comparative Analysis of Hybrid Systems for on-grid and off-grid Applications in Tunisia: case study of Audiovisual chain

Abstract

In this paper, a techno-economic and environmental analysis was conducted to determine the feasibility of designing various models of hybrid power systems. Two hybrid systems (wind-solar with batteries) were developed: grid-connected and off-grid, with a diesel generator for emergency power. These configurations have been analysed using the Hybrid Multi-Energy Resource Optimization software which determine the emissions of pollutant gases, simulates and optimizes energy consumption according to energy demand and resources. For the financial analysis, the net present costs, O&M costs and Total Cost of Energy per unit were calculated. Both configurations were developed for the energy demand of an audiovisual chain. The results obtained show that the first system is the most cost effective due to for its implementation considering the energy production capacity, cost of energy, gas emissions and Net Present Cost.
