In this particular study, the power system consists of a power electronic converter supplied by a battery bank, which is used to form the ac grid (grid former converter), an energy source based on a wind turbine with its respective power electronic converter (grid supplier converter), and the power consumers (loads). The main objective of this proposed strategy is to control the state of charge of the battery bank limiting the voltage on its terminals by controlling the power generated by the energy sources. This is done without using dump loads or any physical communication among the power electronic converters or the individual energy source controllers. The electrical frequency of the microgrid is used to inform the power sources and their respective converters about the amount of power that they need to generate in order to maintain the battery-bank charging voltage below or equal its maximum allowable limit. Experimental results are presented to show the feasibility of the proposed control strategy.

This has happened mostly due to the high cost associated with the expansion of the conventional power grid to these communities. In some cases, technical and environmental constraints also have been factors that have prevented the full electrical service in these communities, particularly those located on oceanic islands. Another application of isolated microgrids occurs when a microgrid is disconnected from the main grid for any reason, in general to improve the local energy reliability. Due to the intermittent nature of renewable energy sources (RESs), the uninterrupted availability of the generation system, and its stand-alone operation, it is required some kind of energy storage system (ESS) in these applications. Although there are several different ESSs, in practical applications, battery banks have been used mainly due to economic reasons. In general, a backup energy source must be used during the lack of the primary renewable energy sources, when the ESS is discharged or when the generation system is under maintenance

One possible solution is to use centralized or distributed resistive dump loads to burn the eventual excess of generated power, is presented. Another possibility is to use physical communication (wiring) between the converters to inform their control systems about the balance of energy in the microgrid and the amount of power that each of them must generate to keep this energy balance under control.

The proposal is to control the terminal voltage of the existing battery banks below or equal its maximum allowable value. This is done by limiting the amount of power that each energy source can generate at each instant. The microgrid frequency is used to characterize the state of charge of the battery bank and quantify to the converters’ control systems how much power they need or can generate to maintain under control the internal power balance of the microgrid. The control of the battery banks’ terminal voltage implies indirectly the control of their SOC

This strategy does not need wired communication between the distributed renewable sources nor dump loads to dissipate the surplus of generated power in the microgrid. These technical advantages make the proposed strategy a promising tool to increase the viability and reliability of the renewable power generation system installed in isolated and remote communities. Although a wind turbine has been used to demonstrate the validity of the proposed strategy, it is also valid regardless of the power source existing in the isolated microgrid. The proposed strategy calculates the amount of power that must be generated at each time by each source in order to keep the balance of energy into the microgrid. In other words, the sum of the generated, consumed, and stored energy must always be zero all the time.
