“…Master-slave control [14][15][16] in a microgrid system comprises a master source and slave sources [17]. The master source is capable of receiving operational information from all the sources based on a communication system, optimizing the microgrid's operating state, and then transmitting control information to the respective slave source.…”

In peer-to-peer controlled hybrid AC/DC microgrids, the grid-connected inverters switch between different control modes with the change of the operating conditions. However, the abovementioned mode transitions trigger transient disturbances in voltage, frequency, and current, causing power mismatch, such that the smooth operation of the microgrid will be hampered. To solve the above-mentioned problems, a composite control strategy is proposed in this study following droop control and PQ control, with the aim of achieving seamless switching between islanded and grid-connected modes. The proposed strategy couples the current inner loops of the above control methods (droop control and PQ control) to develop a dual-mode combined controller operating based on current tracking. This configuration enables the reference current of the input current inner loop controller to track the pre-switching state while maintaining the correct initial value. Moreover, a compensatory pre-synchronization control strategy is developed to cope with variations in frequency, phase, and amplitude. The voltage offset is improved from 19% to synchronize with the grid, and the microgrid islanded/grid-connected mode is smoothly switched. The reference value of the outer loop is changed by PQ control, so that the exchange power of the grid side and the microgrid side is 0. Thus, seamless switching between grid-connected and islanded modes can be achieved. The effectiveness and feasibility of the control strategy proposed in this study are verified in the simulation system.

In this paper, we propose a distributed secondary FM control method for microgrids to address the problem that the operating cost of microgrids increases significantly under load dropout and use the consistency algorithm to make the system reasonably distribute the load power to re-achieve the stable state. In the actual microgrid, the communication delay discusses the influence of information transmission and system stability. Simulation experiments are used to verify and set different convergence coefficients to obtain a suitable range of convergence coefficients. Then, the microgrid economic power allocation algorithm was used to describe the operating cost of microsources and limit the generator output power of the microgrid system to obtain the microgrid economic power allocation values. The cost amount of MG1 is $1327.3 in the equal micro-increase rate consistency calculation. The control condition test reduced 73.14 kWh in the overall load outage of intelligent microgrid control. The power system’s efficiency can be improved through a control method using intelligent information processing.
