Models Used in ENEL (Italian Electricity Board) Transmission Expansion Planning.

摘要

The streamlining of the basic computing programs, utilized for studying the expansion of the E.H.V. transmission network, assumes a very important role as they must necessarily be concatenated to draw from the same data base source and to allow the automatic exchange of data and results from one program to another. This report describes, in detail, two models that, even though utilized by ENEL for many years, nevertheless present some interesting features that have recently received worldwide interest in the design of digital models employed in transmission planning. The first program, named LODEN, explores the problem of the automatic and optimal expansion of a meshed network spread over many years. It finds application in the long term expansion studies (Strategic Planning), before entering in the detailed studies of power systems. The second program, named SICRET, deals with the problem of an accurate and quantitative evaluation of the static reliability (or adequacy) of the power system. It has been based on the Monte Carlo simulation of a year-long system operation, taking into account various random variables, such as line and generator outages. (ERA citation 14:004601)
