Coordinated Strategy for SVC Operation: Ecuadorian Case

This paper proposes a coordinated strategy for SVC operation in terms of SVC optimal reactive power reserve, dispatching of uneconomical forced thermal generation, and transmission system voltage quality. First, an operation strategy is developed at steady state operation to then find the dynamic response at N-l contingencies. A coordinated strategy is performed by evaluating the impact of the SVC operation at not only the controlled bus but the entire transmission system. This work constitutes a relevant base for analysing operation strategies for FACTS devices with an integral view (that is the impact on the wide area of the power system) and not just considering the local effects. The proposed operation strategy is validated on Ecuador realistic data with the aim to get the most benefits of such devices in coordination with other power system apparatus.
