METHOD AND SYSTEM FOR OPERATING AN ELECTRICAL GRID

A method and controller are provided for operating an isolated or weakly connected electrical grid supplied by at least one fluctuating renewable energy source, such as wind or photovoltaic generation, in combination with a grid-forming controllable inverter coupled to a battery. The inverter operates as a master controller to regulate grid frequency and voltage, while the renewable sources operate as slaves. Battery charging and discharging are controlled according to deviations in grid frequency and charge level, with slopes defined for smooth power transitions. Additional selectively driven or non-driven alternators may be coupled in parallel with the inverter to stabilize frequency, provide inertia, reactive power, and short-circuit capacity, or support load changes. Control logic further manages integration of combustion engine-driven generators, resistive load banks, and external energy banks, while accounting for battery temperature and charge thresholds, thereby ensuring stable grid operation under fluctuating generation and demand conditions.
