"The day-ahead market" (spot) is one of the main segments of the competitive electricity market model, the implementation of which is carried out today in Ukraine. Its operation is provided on the power exchange. Mathematically, for the implementation of the spot on the power exchange, the problem of determining the balance between electricity supply and demand is solved. It is based on the determination of a point of intersection of the demand and supply curves by calculating the result of a bilateral auction. The aim is to achieve a maximum "welfare function" of the spot in determining a marginal price and the equilibrium amount of electricity for each billing period. In addition to maximizing the total welfare, the purpose of the spot is to increase the liquidity of the power exchange and to reduce of electricity prices on the electricity market on the whole by reducing the electricity trading volume on the balancing market.A method developed to minimize the level of marginal price on the spot through the optimization distribution of independent price offers of electricity manufacturers is presented. It allows one to ensure a uniform reduction of the marginal price on the spot at the most expensive hours of the day and to provide an increase in the liquidity of the power exchange. In turn, this affects a reduction in trading volumes on the balancing market at a priori high prices and affects the price abatement on the competitive electricity market on the whole.
