Distributed frequency control with partial information using MT-HVDE grids and WPPs

Abstract

Expansion of offshore wind power and the use of high voltage direct current (HVdc) technologies in power transmission are modifying the power system dynamics making them more sensitive to power disturbances. Thus, in order to ensure a power system secure and stable operation, transmission system operators require wind power and HVdc systems to provide ancillary services such as frequency support. In this paper, a distributed control scheme is proposed to coordinate the contribution of wind power plants (WPPs) to mitigate frequency deviations in isolated ac synchronous areas connected through a multiterminal HVdc grid. The control scheme aims to share the power reserves with limited information exchange.
