Optimal load sharing strategy in system of multiple source based on model control predictive

摘要

This manuscript describes the control of the energy transfers in Systems of Multiple Sources of Energy (SMSE). The considered SMSE is a Linear Time Varying (LTV) system in view of the sources and load fluctuations. The proposed control scheme has two levels. The first is used to regulate the DC bus voltage and the current of each source. It is carried out by generalized adaptive PID controllers. The second level determines automatically the power rate associated with each source. The calculation of the power rate is computed with a Model Predictive Controller (MPC) designed to optimize the cost per kWh produced by the system. Simulations are performed using measurements taken over the village of Gandon in Senegal.
