An Energy Trading Model for a Lab-scale PV Microgrid in the Tunisian Context
Abstract
The paper proposes an energy trading strategy that emulates residential building electrification through a lab-scale microgrid in Tunisia. A Mid-Market Rate (MMR) model is proposed for a 10kW grid-connected PV microgrid including battery storage and emulated loads. The trading algorithm proposes a uniform trading price for both electricity export and import within the microgrid. Multiple scenarios are formulated with regard to load profile, system sizing, and electricity market conditions. The results are analyzed and a set of Key Performance Indicators (KPIs) are defined to compare the proposed scenarios. The preliminary analysis shows that the proposed algorithm reduces the CO2 emissions of the microgrid by 24% and improves the self-consumption of the locally generated energy. The model can be scaled up to include local communities effectively.
