State estimation of a discernible active distribution network is researched. A system is discernible if the state of the network can be completely ascertained. An active distribution network is one that includes Distributed Generation (DG) units. A modified IEEE34-node test feeder including two DG units is analyzed. The forward-backward sweep technique provides the state estimation measurement data...
Availability of data from Phasor Measurement Units (PMUs), characterized by their high accuracy to measure node voltage phasors, allows a simplification of the State Estimation (SE) problems. In this paper Iterated Kaiman Filter (IKF) algorithm, as a new method, has been used for SE of a test Active Distributed Network (ADN) integrating PMU measurements. In order to validate the results, Weighted...
This paper presents an effective evolutionary method to solve the Economic Dispatch (ED) problem with units having prohibited operating zones. The Kalman filter is an efficient recursive filter that estimates the state of a dynamic system from a series of noisy measurements in theTotal Power Generation (TPG). ED is an example of a dynamic system algorithm that has been widely used for determination...
Interconnection of Distributed Generation (DG) using renewable resources to the distribution networks in on the rise. Distribution grids having DG interconnections at higher penetration levels are challenged for more accurate monitoring and controls. In this paper a novel approach and a theoretical formulation of state estimation is proposed for distribution grids with Renewable Energy Sources (RES)...
