New requirements and approaches to the long-term forecasting of electricity prices

The paper describes a multi-stage approach that includes: determination of dynamics of the minimum offer prices, that provide loss-free operation and expansion of generation companies; simulation of competition among these companies in the regional energy markets; consideration for a corrective effect the electricity price may have on demand. The calculation results of the long-term price dynamics are given for two scenarios of the economy development and study of the influence the various factors have on electricity cost.
