Abstract
This chapter presents the design of a wide-area damping control (WADC) using a power system stabiliser (PSS) and remote PMU data from the wide-area measurement system (WAMS). The WAMS and monitoring architectures are described, and the common linear design techniques for proposing the WADC are introduced. An offline heuristic optimisation method is used to tune the WADC-PSS control parameters based on modal analysis. Generators’ speed deviation is set as non-local inputs to PSS of the generators for WADC. PMU-based WADC improves damping of both the inter-area and the local oscillatory modes. A four-machine two-area power system is selected for numerical simulation using DIgSILENT PowerFactory. Modal analysis and time-domain simulation confirm the improved performance of the proposed WADC.
