Outdoor power supply modification and expansion

What is an optimum power system expansion plan?

The package is designed to find the "optimum" power system expansion plan within established constraints. By "optimum" is meant that the discounted cash flow (capital and operating expenses) is minimized over a given period with provision made to reduce the effects of uncertainties beyond that period.

What is power system planning?

Its objective is therefore to determine a minimum cost strategy for long-range expansion of the generation, transmission and distribution systems adequate to supply the load forecast within a set of technical, economic and political constraints. Traditionally, power system planning has been mainly related to generation expansion planning.

How do you evaluate a power expansion programme?

Determine the optimum (minimum cost) expansion programme. Determine the sensitivity of the results to variations in the economic data. Estimate the financing requirements for a selected power expansion programme. Check for transmission system and operational constraints. Check for financial constraints.

What are the steps involved in a power system expansion study?

The steps involved in a power system expansion study using the WASP package are shown schematically in Figures 1 and 2. Briefly, these are as follows: Correlate historical data which might be used to forecast the future demand for electricity.

Do all electric power expansion programmes offer the same benefits?

This is tantamount to assuming that all programmes of electric power expansion meeting projected demand with the imposed constraints on reliability offer the same total benefits and that the least-cost programme is consequently the most advantageous for the ultimate consumers.

Why are mathematical models used in electric system expansion problems?

Because of the many variables involved in electric system expansion problems, many mathematical models have been developed by planners in order to tackle the prqblem in a systematic way. Refs.[1 ], .
