RELIABILITY ASSESSMENT AND PLANNING FOR DISTRIBUTION SYSTEMS - NEW GLOBAL APPROACH

摘要

Hydro-Quebec has used a new approach for Reliability Assessment with a prototype called FIORD, a French acronym for a global reliability assessment system. What were the context and the reasons for these new developments? What's new in this approach? How does it work? What did it bring? In the context of recommending a distribution MV grid automation program, Hydro-Quebec had to evaluate the benefits of various automation scenarios in order to compare the expected improvements with the present situation. The study had to cover the entire distribution MV grid, using input data representing correctly the present situation and simulation techniques which are sensitive to various scenarios according to the improvements brought by new technologies. In order to fulfill these requirements, a new global approach had to be introduced.
