Bulk electric load cost calculation methods : Iraqi network comparative study

Abstract EN

It is vital in any industry to regain the spent capitals plus running costs and a margin of profits for the industry to flourish.

The electricity industry is an everyday life touching industry which follows the same finance-economic strategy.

Cost allocation is a major issue in all sectors of the electric industry, viz, generation, transmission and distribution.

Generation and distribution service costing’s well documented in the literature, while the transmission share is still of need for research.

In this work, the cost of supplying a bulk electric load connected to the EHV system is calculated.

A sample basic lump-average method is used to provide a rough costing guide.

Also, two transmission pricing methods are employed, namely, the postagestamp and the load-flow based MW-distance methods to calculate transmission share in the total cost of each individual bulk load.

The three costing methods results are then analyzed and compared for the 400kV Iraqi power grid considered for a case study
