Abstract

This paper proposes a solution for automatic service restoration along with automatic fault location and isolation of the faulty sections in feeder in a power distribution system. A Java agent development environment-based multiagent system (MAS) is proposed to solve the problem of automatic service restoration in smart grid distribution systems. The agent-based solution development is discussed in detail and the MAS application to solve power restoration problem is elaborated in this paper. A study is done on a modified IEEE 33 bus system and the solution is implemented in the Velachery substation of the Tamilnadu electricity board. The results prove that fast and effective fault location, isolation and service restoration is achieved using the proposed solution.

Highlights

With the increase in the size of power infrastructure, the complexity of the power distribution has increased multi fold. This is due to the inevitable increase in the demand for electric power
In cases of manually controlled grids, upstream sections are restored by closing the recloser after manual detection and isolation of the faulty section
Once the fault is located and isolated, all the feeder sections in the faulty feeder are disconnected to start service restoration. This is done through signals sent to the physical layer to open the smart switches at both ends of all feeder sections in the faulty feeder

Summary

Introduction

With the increase in the size of power infrastructure, the complexity of the power distribution has increased multi fold. Based on the indicator status response from the upstream and downstream switches, the FSA calculates feeder section fault indicators Once the fault is located and isolated, all the feeder sections in the faulty feeder are disconnected to start service restoration This is done through signals sent to the physical layer to open the smart switches at both ends of all feeder sections in the faulty feeder. Recloser agent sends an ACCEPT-PROPOSAL to the feeder section agent corresponding to the selected tie switch, and the FSA communicates with the physical layer to effectuate the switch operation. It is evident that the voltages of the buses after network reconfiguration are well within the agreed voltage thresholds
