Abstract

The publication [1] provides a unique parallel solution for electrical power system state estimation called Vertical Division State Estimation technique (VDSE). In this technique the measurements are grouped around the node clusters and processed independently, whereas in conventional state estimation whole power system network is considered as single entity and that is why the computational time required is considerably large. For real time EMS application state estimator is the integral part and it should be capable of giving the estimation of state variable in very short interval of time. To address this issue various techniques are developed such as dynamic state estimation, tracking, AI technique, multi-area technique, Two Level state estimation (TLSE) etc. In TLSE technique the power system network is sub-divided into smaller area such that each sub network can be processed independently. The publication [2] shows the application of VDSE on to TLSE. This paper presents the application of VDSE technique on to super node area level. A node along with its connected nodes is called node area and combination of two node areas is called “Super Node Area”. By applying VDSE to super node area cluster the number of parallel processors required can be reduced drastically while keeping the computational time within limit. The concept is tested on 13 and 30 bus IEEE test system and compared with ISE and Node level SE.
