DISCRETE-CONTINUOUS MODELS IN THE WHOLESALE ELECTRICITY MACROREGION MARKET MODELING
Discrete-continuous wholesale electricity market operating model with cross-effect of electricity price and load is suggested in the article. Model identification method is proposed and applied on the united power system of the Urals' data. The significance of estimated parameters is proved by stable behavior of parameters, performed on subsample. The calculations are performed on base of weekly data from 2011 to 2014 year and the seasonal effects are included in the model due to weather variables. The results indicate that hypothesis of inelasticity of demand is not rejected and significance of such technological parameter as frequency is confirmed. The hypothesis of non-linear influence of temperature on electricity demand is not rejected.
