A Case Study on Corrective Measures of Secondary Control Assisted Microgrids
Year: 2025
Type: article
Abstract: Flexibility and efficiency are the qualities of microgrids which are associated with power delivery and intended to create a system which can adapt to changes in distributed generation output and load demand in an effective and timely way, without sacrificing stability or performance. In order to maintain the power quality requirements, microgrid control solutions should be reliable enough to operate both independently and in conjunction with the utility power network. The paper proposes secondary layer control function in the control hierarchy of microgrid and mechanism behind its implementation to correct frequency and voltage deviations resulted through primary control. Two network forming inverters, feeding a common load are considered for this study. A discretized SVM (space vector modulation) technique is utilized owing to advantages such as high utilization of DC link voltage and low output voltage total harmonic distortion, to convert the modulating signals into pulses for driving the power electronics-based converter/inverter. Computer simulations (Reactive/active power sharing, frequency, voltage, current and voltage tracking versus time) are performed on MATLAB-Simulink software to evaluate the efficacy of the proposed approach.
