This paper presents a control strategy for DC-DC converter interfaced supercapacitors (SC) in photovoltaic (PV) based microgrids (MGs) for mitigating the sharp power drop effect due to irradiation change on the DC voltage and reducing the impact on Battery Energy Storage Systems (BESS). Most dispatchable generation sources other than BESS have a long response-time and cannot restore the power balance quickly. Additionally, to reduce the large stress inflicted on BESS during PV power loss, an SC based solution is proposed in this paper. A Model Predictive Controller (MPC) is designed to give a fast response during irradiation change in order to compensate for the power loss induced by PV generation resources. A study case composed of PV and BESS based DC microgrid is explored where the usage of this control strategy demonstrates clear benefits for mitigating aggressive DC-Link voltage transients and improve the overall stability of the MG.
