Abstract

Nowadays, electricity systems have grown from offering basic electricity services to giving highest quality standards facilities. Today customers have an added value, in Costa Rica´s case, they are regulated by ARESEP. This institution supervises parameters of quality, service and prices, it is therefore necessary a control and regulation of frequency-voltage variables. This investigation proposes a new rate model from its own research begun part-A that is used as a reference. Looking for electricity’s cost decrease, a linear optimization is the solution to carry out an economic dispatch of the reactive power and through the correct mechanisms, customers will take advantage of a segregated rate.

Keywords: Electric rates; reactive power charging; reactive power prices.
