Analysis of the daily electricity consumption schedule optimization opportunities

Purpose. Explore the possibilities of management programs usage to control electricity demand in Ukraine. To develop an optimization mathematical model of the power consumption regime based on key indicators of the consumption schedule estimation and equipment flexibility factors. Methodology. Proved that as a result of demand side management programs for electricity are benefit of only for consumers and energy companies, but also for a whole society. Classification of demandmanagement programs for electricity according to spheres of action presented. The article deals with the method for electricity consumption daily schedule optimization while implementing electricity demand management programs. Findings. The effects of demand management programs implementation and reducing consumption schedule unevenness problems based on optimization task with the schedule coefficient and the cost of electric energy reduction have been analyzed. The conducted variants research of demand side management programs influence on possibilities of electric energy consumption schedule modification confirmed the possibilities of increasing power systems functioning efficiency. Originality. Optimized energy consumption graphs are obtained based on key indicators for a group of the same type consumers, considering consumer interests, which enables to assess the effect demand side management programs implementation. Consumers peculiarities are considered by coefficient of their demand flexibility kг. Practical value. The mechanism for the DSM innovation programs for optimizing power consumption regimes introduction possibility evaluation has been obtained. Established that domestic electric energy consumers have a significant potential for peak consumption reduction by usage of demand side management programs aimed at costs reduction for consumers and increasing the electrical consumption schedule filling ratio for energy companies
