Distribution automation leading to a smarter grid

In the delivery of electricity from the generating station to the consumers, Power Distribution System (PDS) plays a major role. Electric power utilities worldwide are adopting the computer aided monitoring, control and management of PDS to provide better services to the consumers. Recent advances in Information Technology and data communication system are being utilized to automate the electric PDS. The next-generation electricity grid, which is the smart grid, is addressing the major shortcomings of the existing grid. In essence, the smart grid envisages providing utility companies with full visibility and control over their assets and services. This paper presents a review of automation of the Power systems with special emphasis on distribution automation, leading to a smarter grid. The distribution automation and distribution management system functions are discussed in detail and the emergence of a smart grid. The wide area monitoring and control implementation in the transmission sector is also touched upon. The paper also provides some insight into the expansion of laboratory facilities for smart grid implementation and research.
