“…Cao et al 20 have analyzed the advantages of SOPs for electrical DNs. A framework for optimal installation of SOP is proposed by Konstantelos et al, 21 which considers the challenges that occurred because of the integration of DGs.

Summary In modern distribution networks (DNs), soft open points (SOPs) are newly introduced power electronic devices that are installed between the adjacent feeders in place of normally open points. The SOPs contribute in Volt/VAr control by accurately adjusting the active power flow and supporting the reactive power from both AC sides. A further step forward alludes to energy storage–integrated SOPs, referred to as E‐SOP, which could significantly influence the active power exchanges through charge/discharge actions in appropriate time intervals, say as the hours with high‐ and low‐price electricity tariffs. Accordingly, E‐SOPs provide a unique opportunity in effective active power control and also Volt/VAr control in the presence of distributed generations (DGs) and renewables. This study proposes a model for day‐ahead operation scheduling of DNs with high penetration of DGs and photovoltaic (PV) considering the installations of E‐SOPs. An accurate linearized model is developed to consider the technical performance of E‐SOP in power flow study. Voltage security, economic, and network emission indices are accounted as a concern of the network operator. To this end, a multi‐objective optimization model is developed based on mixed‐integer linear programming being tackled by an augmented ε‐constraint method. For assessing the effectiveness of the developed model, it is simulated on the IEEE 33‐node test system; however, the IEEE 119‐node test system is also tailored to assess the scalability issues. The obtained results are mainly represented in terms of smart charge/discharge and effective VAr support of E‐SOPs, reduced operation cost, improved voltage profile, and a reduced emission level.

“…The entropy weight method is a method for determining the weight according to the amount of information transmitted by each indicator to the decision maker [6]. The larger the difference between an indicator, the smaller the entropy value, and the more information the indicator contains and transmits, the greater the corresponding weight.…”

In order to improve the ability of resource optimization configuration in the development of distribution network, and clarify the investment direction and management focus, an evaluation index system model of distribution network benefit considering input-output relationship is put forward. Firstly, with the consideration of the input-output relationship, an input-output evaluation index system for a different category of distribution network is built. Secondly, through the relevance analysis of the distribution project, an input-output benefit evaluation model of the distribution network is established based on the comprehensive empowerment method. On this basis, the basic input-output data of the distribution network in the three cities of a certain province is selected to verify the example, and the sensitivity analysis is carried out for the evaluation categories of the cities. The results prove the effectiveness of the proposed method, and provide reference for the grid enterprises to scientifically and rationally allocate the investment of distribution network.

“…It was shown in [20] that SOP facilitated the economic operation of ADNs, and network performance was improved by considering both SOP and network reconfiguration. Reference [21] proposed a planning model that considers optimal investment of SOP as well as various smart technologies to alleviate the network constraints violation due to DG penetration. Considering the high investment of SOP, it is of significance to optimize the siting and sizing of SOP to realize maximum benefits in ADNs [22].…”

A coordinated control method of voltage and reactive power for active distribution net-works based on soft open point. Abstract-The increasing penetration of distributed generators (DGs) exacerbates the risk of voltage violations in active distribution networks (ADNs). The conventional voltage regulation devices limited by the physical constraints are difficult to meet the requirement of real-time voltage and VAR control (VVC) with high precision when DGs fluctuate frequently. However, soft open point (SOP), a flexible power electronic device, can be used as the continuous reactive power source to realize the fast voltage regulation. Considering the cooperation of SOP and multiple regulation devices, this paper proposes a coordinated VVC method based on SOP for ADNs. First, a time-series model of coordinated VVC is developed to minimize operation costs and eliminate voltage violations of ADNs. Then, by applying the linearization and conic relaxation, the original nonconvex mixed-integer nonlinear optimization model is converted into a mixed-integer second-order cone programming model which can be efficiently solved to meet the requirement of voltage regulation rapidity. Case studies are carried out on the IEEE 33-node system and IEEE 123-node system to illustrate the effectiveness of the proposed method. Index Terms-Active distribution network (ADN), distributed generator (DG), mixed-integer second-order cone programming (MISOCP), soft open point (SOP), voltage and VAR control (VVC). NOMENCLATURE Sets Ω bSet of branches without OLTC Ω O Set of branches with OLTC Variables P t,ij , Q t,ij Active/reactive power flow of branch ij without OLTC at period t
