In order to address the power quality enhancement in a given microgrid, independent control of reactive, unbalanced and distorted load current components, in a multi-inverter-based approach may be required. Therefore, this paper proposes a coordinated control strategy using the Conservative Power Theory (CPT) and assuming the contribution of all grid connected interfaces, especially those related...
This paper proposes distributed noise resilient techniques for the secondary voltage and frequency control of AC microgrids. The effect of noise in reference signal on the synchronization process is studied. The same communication topology for the secondary control is adopted to implement noiseresilient algorithms. The efficacy of the consensus filters and distributed least mean-square algorithm for...
The microgrid's control strategies are designed to achieve the power sharing, as well as to regulate voltage and frequency within acceptable ranges. To fully meet these requirements, a distributed cooperative control strategy for multiple Electric Springs (ESs) is proposed in this paper. By ensuring the reactive power utilization ratio of each ES to converge to the given set point, the tradeoff between...
In multi-inverter-based islanded microgrids with unbalanced and distorted loads, due to voltage drop across line, the load bus voltage is unbalanced and distorted, which shows the requirement for power quality increase at load bus. To address this problem, this paper presents master-slave-based cooperative operation of DGs with the implementation of Conservative Power Theory (CPT), in which in addition...
