“…In literature, three main schemes have been reported and employed for energy demand reduction, namely, VVC, [5][6][7][8][9][10][11] CVR, [12][13][14][15] and DNR. [16][17][18][19][20][21] The first scheme, VVC, refers to maintaining the voltage within permissible limits throughout the feeder length using voltage-regulating devices and reactive power control.…”

“…10 Minimization of apparent energy losses in a distribution system with the help of optimal settings of VVC devices considering various load models has been presented in Satsangi and Kumbhar. 11 However, the reported methods in the above-discussed literatures [5][6][7][8][9][10][11] have focused on minimization system losses and operating and maintaining cost considering additional power devices. However, these methods lack the achievement of higher energy savings and peak clipping with proper feeder voltage profile.…”

“…Peak demand reduction and energy savings have been achieved through CVR operation considering photovoltaic (PV) smart inverter in Singh and Singh. 15 However, the operation of traditional VVC devices such as OLTC, VRs, and SCBs employed in previous studies [5][6][7][8][9][10][11][12][13][14] are limited because of their physical constraints. Further, these devices fail to operate under sudden change in network because of its slow operation nature.…”

Summary Reduction in greenhouse gases and electricity is a major concern of developing countries in the present scenario. Therefore, energy demand reduction through conservation voltage reduction (CVR) scheme can play a prominent role in such concerns because a major share of energy demand in developing countries is still met by conventional coal/fuel‐based power plants. Moreover, it does not require the participation of consumers to achieve energy saving, unlike in demand side management. Therefore, in this paper, a coordinated scheme comprising multiple voltage‐regulated devices such as on‐load tap changer (OLTC) transformer and switched capacitor banks (SCBs) including distribution network reconfiguration (DNR) operation for CVR has been proposed with minimum operating cost in distribution system. In addition, the impact of a flexible power electronic device called soft open point (SOP) has been investigated during CVR operation. The objective function of the proposed coordinated CVR scheme is to minimize the operating cost, which include the energy demand cost, switching operating cost of OLTC, SCBs, and remote‐controlled switches (RCSs), carbon emission cost, and operating and maintenance costs of SOP, while satisfying the system operational constraints. Further, the impact of high penetration of photovoltaic (PV) distributed generation on the proposed coordinated scheme has been studied. Besides, local reactive power voltage (Q‐V) control strategy of the SOP inverter has been proposed to mitigate voltage violations during cloudy day conditions. The present optimization problem has been solved using modified binary grey wolf optimization (MBGWO) algorithm. The performance of the proposed scheme has also been verified considering the forecast errors in PV generation and load demand. The proposed coordinated CVR scheme has been implemented on a modified 69‐bus distribution system. The test results demonstrate the significance of the coordinated scheme for the minimization of daily operating cost. The comparative study reveals that the combined impacts of CVR, DNR, and SOP are more beneficial than that of either CVR, DNR, or SOP operation.
