Although much of today's power system remains steady, the integrations of wind power make a portion of the system become fluctuant. To monitor these fluctuations, we need to utilize phasor measurements and shorten the time interval for state estimation. On the other hand, however, this means huge increase in computation burden. As a tradeoff between accuracy and computation efficiency, a multi-time...
High-voltage transmission networks are commonly equipped with phasor measurement units (PMU), and some of them are PMU observable. However, PMUs are seldom installed in distribution networks due to budget limitations. The state estimation equations of PMU observable areas are linear, while those of other areas remain nonlinear. This paper proposes a new distributed state estimation method for solving...
An on-line forecasting algorithm for transient stability of power systems, based on real-time measured fault impedance and EMS, is put forward in this paper. The proposed algorithm combines PMU measurements and EMS models organically. Models, initial states and fault information are three basic aspects of time-domain simulation for transient stability. Once a fault occurs, models and initial states...
A transient stability on-line forecasting algorithm, based on PMU measurements and EMS models, is proposed in this paper. This algorithm makes full use of both fast speed of PMU measurements and detailed models of EMS, which could deal with the situations with single fault or cascading faults. Several main factors that affect the accuracy of the forecasting algorithm are studied, and a binary search...
