Coordinative Frequency Control of Multi HVDC Links in Sending-End Power Grid Considering Over-Frequency Protection of Wind Power Generation
A large number of high voltage direct current (HVDC) projects are under construction or have been put into operation in order to mitigate the reverse distribution between energy and loads in China. Focusing on the over-frequency scenarios of sending-end power systems causing by HVDC blocking, the co...

| description | A large number of high voltage direct current (HVDC) projects are under construction or have been put into operation in order to mitigate the reverse distribution between energy and loads in China. Focusing on the over-frequency scenarios of sending-end power systems causing by HVDC blocking, the coordinative control of multi high voltage direct current (HVDC) links considering over-frequency protection of wind power generators is studied in this paper to control system frequency. A coordinative control model is proposed to minimize the total HVDC modulation amount. The first-order difference is adopted to estimate the sensitivity of the maximum frequency deviation of the system against each controlled DC power, and the optimum coordinative frequency control strategies of multi HVDC links can be obtained. The proposed method is validated in a sending-end power grid model with high wind power penetration rate to show its effectiveness in designing the frequency control strategies of the sending-end power systems. |
