“…In [8], an analytic hierarchy process strategy and binary ant colony optimization algorithm were utilized to solve the multiobjective daily VVC of distribution systems. Oshiro et al [9] proposed a combined genetic algorithm and tabu search (TS) approach for optimal voltage control taking into consideration the coordination of DGs, the load ratio control transformers, step voltage regulators, Sh.Cs, shunt reactors, and static Var compensators. In [10], a dynamic programming algorithm was used to solve the VVC problem, in which the DG output voltage was dispatched cooperatively with the operation of the OLTC and the Sh.Cs.…”

Distributed energy resources (DERs), if properly coordinated with other Volt/Var control (VVC) devices, could be incorporated in daily VVC problem. In this paper, a new 2-stage model is presented for daily VVC of distribution systems including DERs, taking into account environmental and economic aspects. First, in the day-ahead market, an initial environmental-economic dispatch is performed to minimize both the electrical energy costs and the gas emissions pertaining to generation units. The initial scheduling results determined by the market operator are delivered to the second stage, namely the daily optimal dispatches of VVC devices, to examine them from operational viewpoints and to yield the daily optimal dispatches of the VVC devices. The objective function of the second stage consists of the total cost of the following components: active power losses, adjustment of the initially scheduled active powers, and depreciation of switchable devices. In this paper, attention is directed towards 2 important types of DERs to be connected to the network: synchronous machine-based distributed generations and wind turbines. Because the active and reactive powers of DERs are coupled via the capability diagram, in this paper, this issue is addressed by considering the capability diagram of DERs in the proposed model. In particular, the Q-capability diagram of wind turbines should be analyzed taking the hourly wind speed fluctuations into consideration, so that delivery of a uniform reactive power can be ensured over the entire hour of operation. Due to the complexity of solving mixed integer nonlinear programming problems, an algorithm based on Benders decomposition is suggested to solve the proposed VVC model in the second stage. Finally, 2 standard distribution test networks are utilized to validate the effectiveness of the proposed method.

“…The most significant challenge that is emerging as a result of the increasing penetration of DG is that of voltage rise [9]. The literature proposes methods of voltage control in areas where DG is deployed in order to resolve violations of voltage limits [10][11][12][13]. However, so far this issue has been addressed only from the perspective of power generation [14][15][16] or the distributed network operator (DNO) [17].…”

“…Some innovative concepts such as microgrids and virtual utilities were presented in [5]. In [6], an optimal control method of distribution voltage with coordination of distributed installations, such as on-load tap changer (OLTC), step voltage regulator (SVR), shunt capacitor (SC), shunt reactor (SR), and static var compensator (SVC) was proposed to minimize voltage variation from the standard value and reduce distribution loss under limited number of operations of control devices. To control the voltage deviation of distribution system caused by DGs, an optimal voltage control methodology by using the tap changing transformer and the inverter based DGs has been proposed in [7].…”
