کلیدواژه: Robust optimization,Info-gap decision theory,Day-ahead market,Real-time market,Two-level optimization
نویسندگان: Aboli Reza, RAMEZANI MARYAM, FALAGHI HAMID
ناشر: مهندسی برق دانشگاه تبریز - Tabriz Journal of Electrical Engineering
In this paper, a hybrid day-ahead Robust optimization model is presented for the optimal operation of active distribution networks subject to real-time operation. Maintaining the convex structure of the problem with load flow equations is the most important goal in how to Robust modeling of uncertai... ادامه

The novel theory of the portfolio optimization has developed based on the fundamental Markowitz model. The Markowitz model is unique in terms of theory, but its weaknesses prevent the use of this model in practice. In this model, the return rate is extracted based on past data, but in this research,... ادامه
