Abstract

Abstract:

ABSTRACT： To design time-of-use (TOU) tariff based on the existing residential multi-step electricity price, and combine the two kinds of prices, which further lead to the rational use of electricity and improve energy efficiency, this paper proposes the optimization model and method of residential TOU tariff calculation under multi-step electricity price. Firstly, according to the user coverage of current each step price, we divide whole residential households into the corresponding sub-group market subdivision. Secondly, we construct the TOU tariff responsive function of every market subdivision, as well as the corresponding optimization objective function set of TOU tariff. Thirdly, we build the constraint condition set of TOU tariff in every market subdivision. Lastly, we construct the TOU tariff optimization model of every segment market with combining the objective function and the constraint condition, whose output result is the optimal TOU tariff for each step. The rationality and feasibility of the model are verified in the example simulation, and the sensitive analysis further reveals the changing law of the optimal TOU tariff results for each step with the demand response.
