Cost Benefit Analysis (CBA) approach of Non-Conventional STATCOM Applications

Abstract

This paper evaluates non-conventional reinforcement options in four areas of the Scottish Power Energy Networks distribution network that are, or are expected to be, experiencing voltage issues. STATCOMs and mechanically switched capacitors have been assessed qualitatively against traditional forms of reinforcement. Cost-benefit analyses have shown that the net present value saving on STATCOM installation can be significant, in comparison to a conventional reinforcement solution, but is highly dependent on the scale, and therefore cost, of the conventional solution.
