In this study, the problem of proportional power sharing consensus in a DC microgrid (MG) consisting of distributed generators (DGs) is discussed. Presently, MGs face challenges involving the intermittent nature of DGs and load power fluctuations. To address these challenges, three different control schemes are proposed. The first consensus-based control algorithm is introduced to address proportional power sharing in the presence of variations in the DGs rate, i.e., power capacity. Secondly, in regards to load power fluctuations, a control scheme is designed to enable the DGs to compute their individual proportional power share in a distributed manner. Eventually, a comprehensive real-time control approach is developed through which the DGs cooperatively maintain the required power load and achieve the updated proportional share simultaneously. To demonstrate the effectiveness of the proposed approaches simulations results for a simple network of DGs are presented.
