Abstract

In this paper, a stochastic model is introduced to study the influence of demand response programs on economic and system security indices in uncertain conditions. The power system under study includes thermal and wind power sources and superconductive magnitude energy storage ‌in which, the uncertainties of load and wind power and stochastic outages of generation units and transmission lines are considered. The problem is formulated through a two stage stochastic optimization model and is solved by utilizing Mixed Integer Linear Programming (MILP) technique. The results of the studies of the 6-bus system illustrates that the employment of energy storage resources and demand response along with the generation reserve not only reduce the costs of operation in power system, but also maintain its security level through managing the uncertainties. Sensitivity analyses show that‌using ‌the ‌appropriate capacity of demand-side reserve not only reduces the cost of the power system ‌but ‌also ‌improve system reliability and avoids additional investment.‌ Moreover, ‌The result‌s ‌show ‌that increasing load forecasting error has more effects on the operation cost of the power system.‌
