One of the most important reasons of smart grids (SGs) is renewable energies (REs) increase and demand response (DR). Present methods are not practical in the case of high REs presence in SGs and should be revised. The flexibility of production is low in SGs with high REs penetration, and loads should follow the production. The increase in the domestic controllable loads (DCLs) flexibility compensates the low flexibility in production. As a result, DR is essential in SGs with high share of REs. This study presents a new method for DR with high REs penetration. Also, a new formulation for electrical appliances is provided in this study, including washing machine, dish washer and heating/cooling system. In the proposed method, the RE resources produced power is considered in addition to loads condition. The controllable loads are transferred to the time when the difference between load and RE generated power is maximum (considering the consumers’ welfare). The results show that applying this method will increase the flexibility of consumption and REs penetration in SGs. The study is performed for the Ekbatan residential complex that includes three smart microgrids and a 63/20 kV substation in Tehran, Iran.
