There is provided a method of operating a renewable power plant that is connected to a wider power network by a bus. The method comprises: identifying a predetermined voltage condition of the renewable power plant or of the bus; controlling the renewable power plant to maintain zero reactive power exchange at the bus for a first period; calculating an average voltage level of the bus that was achieved during the first period; and controlling the renewable power plant to maintain the voltage output at a set voltage level for a second period, the set voltage level being substantially equal to the calculated average voltage level. The method ensures that voltage oscillations due to a push-pull phenomenon between a power plant controller and the power network do not upset the stability of the grid.

Adaptive control for networked renewable power plants

A method for controlling a renewable energy power plant comprising a plurality of wind turbine generators, the method comprising: measuring a voltage level associated with a point of interconnection between a power transmission network and the power plant; calculating a reactive power exchange limit based upon the measured voltage level; and controlling the power plant so that the calculated reactive power exchange limit is not exceeded.
