Active Voltage Regulation with Grid Controller Existing voltage control systems such as line drop compensation may no longer be suitable if generation is connected to the feeder. Overvoltage situations have a negative impact on the service life of electrical devices, cause higher technical losses and can trigger the feeder line / transformer safeguards.

Active Voltage Regulation with Grid Controller Introducing real-time measurement, VR, BESS, STATCOM or similar controllable elements one can automate the distribution network management by introducing Grid Controller managing the voltage regulator, P/Q compensation with battery storage, etc. based on current demand & supply needs on the observed part of the distribution network.
