Thermoelectric generation re-dispatch through Online Stability Assessment in altered grid conditions

Abstract

This article presents the design, algorithms, and results obtained situations not foreseen by the operating procedures, through the use of a real-time assessment analysis tool to perform change of generation of thermoelectric plants in a configuration denominated as an altered grid, which may impact the excellent performance of Systemic Special Protection Schemes implemented by power system operation planning. Thus, through the analysis of the security region, control center operators may have the adequate allowance, in real-time, to perform a new and precise generation request and thus avoid instabilities as well as overload in the electric system under analysis, especially prolonged interruptions of electricity for consumers.
