Energy Management in Multi-Source Power System Based on PV /Wind /Batteries / Diesel Generator Connected with the Grid

Renewable Energy Resources represent the most optimal approaches available today to combat the ever-increasing risks of climate change and global warming. Among the most crucial sources of such energy resources are Wind and Solar energies, which boast a relatively high level of efficiency. These ecologically friendly power resources are employed in the technology of Distributed Generation units, which pertains to the incorporation of contemporary power sources that directly interface with micro and smaller capacity power generating units. These units are typically installed in the distribution segment of a power system or any location where energy consumers and loads are concentrated. In this work, hybrid renewable sources, batteries, and diesel were integrated with the grid system. The operating priority is given to the hybrid renewable sources, while connecting the maximum power tracking point (MPPT) to those sources. The particle swarm algorithm (PSO) was used through which we can obtain the greatest capacity. The network connection is with Loads: In the event of a sudden malfunction in the inverter and the generator is not ready, it will be necessary to connect the network to feed the loads until the malfunction is repaired and the system returns to its normal state. Power management is based on the droop control strategy of the inverter, which in turn maintains the stability of the system. A simulation study is conducted to evaluate the performance of the system as proposed, utilizing MATLAB Simulink. The obtained simulation results are subsequently presented for analysis.
