ENEL (Italian Electricity Board) Generation Planning: Models.

摘要

The problem of generation system planning, even in the ''bus-bar'' configuration, is a complex one, since many technical-economical parameters are to be handled at the same time: some of them, moreover, are ruled by random laws and all are mutually interacting. ENEL has devoted, since its foundation, considerable activity to the development of suitable models of generation systems and of their components, as well as, to the relevant computing programs which permit the examination of large systems. Particular attention has been devoted to the quantitative evaluation of system reliability by means of suitable risk indexes (high values of risk indices correspond to low levels of reliability). By assigning a unit cost-of-risk, the overall risk cost constitutes, with capital cost and operating cost, the factors upon which the system optimization is based. The paper describes the main characteristics of the two digital models utilized at ENEL for generation system planning: the WAT program for generation expansion studies and the SICIDR CARTER program for operational planning.
