Abstract: 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.

Abstract: A power plant control system for a first renewable energy power plant comprising one or more renewable energy generators. The power plant control system comprises receiving means for receiving a power delivery demand from a transmission grid operator; control means configured to control the one or more renewable energy generators of the first renewable energy power plant so as to supply power that targets the received power delivery demand; and communication means configured to transmit a request to one or more further renewable energy power plant control systems to request operation of one or more power compensation units associated with respective ones of the further renewable energy power plants. The embodiments of the invention are beneficial in that the power plant control system of the first renewable energy power plant has the functionality to manage the power delivery across multiple power plants, and therefore acts as an energy management system, able to active assets of other power plants so as to react quickly to any grid instabilities that may be detected. This provides a robust response to grid instabilities. The invention has particular utility to wind power plants, but also applies to other types of renewable energy power plants, for example photo-voltaic power plants, hydro-electric power plants and the like.
