Description

The notions of intelligent and automated power systems have gained cur-rency in recent years. All over the world increasing attention is being paid to smart grids. New circuit topologies, new monitoring and control equipment, and new automation devices will be necessary, which would allow better monitoring, control, maintenance and simulation of the electrical distribution system. But the advent of integrated sensor and monitoring systems for Advanced Distribution Automation raise a lot of questions concerning the integration and strategic use of such new intelligent devices. Will it be an incremental or evolutionary change or a radical shift? What could be in for me? What about the business case?

The forces for change acting on the distribution system are driven by con-sumers, technology and the overall business environment. Considerable change in utility environments is expected in the next years including con-sumer demand for improved reliability, changing consumer load character-istics, higher marginal cost of losses, and increased distributed resources.
