Soft open point-based energy storage (SOP-based ES) can transfer power in time and space and also regulate reactive power. These characteristics help promote the integration of distributed generations (DGs) and reduce the operating cost of active distribution networks (ADNs). Therefore, this work proposed an optimal operation model for SOP-based ES in ADNs by considering the battery lifetime. First, the active and reactive power equations of SOP-based ES and battery degradation cost were modeled. Then, the optimal operation model that includes the operation cost of ADNs, loss cost, and battery degradation cost was established. The mixed integer nonlinear programming model was transformed to a mixed integer linear programming model derived through linearization treatment. Finally, the feasibility and effectiveness of the proposed optimization model are verified by the IEEE33 node system.

In this paper, the interaction between energy sellers and buyers in utilizing active distribution networks is modeled with considering two networked and non-networked modes of microgrids (MGs). A retail electricity market is modeled as a bi-level problem. Accordingly, the Distribution Company (DISCO) in the upper level in order to maximize the profit offers an optimal price to MGs. While in the lower level, the MGs to compare the offered prices by DISCO with the prices of MGs generation sources for minimizing the total costs decided to whether to buy from the DISCO or not. As the first contribution of the paper is to consider the networked operation of the MGs under a unique beneficiary of MGs (BMG). As the second contribution, two very important indices reserve and self-adequacy are considered, which are necessary in the problems related to MGs. In this paper, the impact of considering and disregarding two important reserve and self-adequacy indices of MGs on the profit of the DISCO in two different scenarios is investigated. In each scenario, the impact of considering two modes networked and non-networked of MGs on the profit of DISCO is investigated. Simulation results show the efficiency the presented model.
