Patent ID: 7680562

Claim:
A power generation system comprising: a converter configured for supplying power from a constrained power or energy source to a power network; and a control system configured as a voltage based control system and configured for balancing instantaneously available power from the constrained source against demanded load from the power network by supplying control signals to the converter for dynamically adjusting power network voltage and power network frequency such that the demanded load is transiently reduced when the demanded load exceeds the instantaneously available power from the constrained source, wherein the control system further comprises a power shaper configured to implement a power limit and a ramp-rate limit consistent with the capability of the constrained source and to provide a power command, an angle regulator configured for receiving the power command and generating an adjustment angle for adjusting a voltage phase angle command of the converter, a phase locked loop for obtaining a voltage angle estimation for following measured power network voltage with minimal steady state error, and a dynamic compensator configured to stabilize the phase locked loop when connected to weak grids or impedance networks.
