Title On feasibility of regional frequency-based emergency control plans
Type JournalPaper
Keywords Frequency regulation-Frequency response model-Load shedding-Emergency control
Abstract Decentralized and regional load-frequency control of power systems operating in normal and near-nor-mal conditions has been well studied; and several analysis/synthesis approaches have been developed during the last few decades. However in contingency and off-normal conditions, the existing emergency control plans, such as under-frequency load shedding, are usually applied in a centralized structure using a different analysis model. This paper discusses the feasibility of using frequency-based emergency control schemes based on tie- line measurements and local information available within a control area. The conventional load-fre- quency control model is generalized by considering the dynamics of emergency control/protection schemes and an analytic approach to analyze the regional frequency response under normal and emergency conditions is presented.
