“…One effective approach is to control the system parameters by formulating the voltage stability issue into the conventional optimal power flow (OPF) problem. us, there is renewed interest to develop the voltage security-constrained optimal power flow (VSC-OPF) approach, ensuring the system is operating at a secure level [4][5][6][7][8].…”

Nowadays, the changes of economic, environment, and regulations are forcing the electric utilities to operate systems at maximum capacity. Therefore, the operation and control of power system to improve the system stability has been receiving a great deal of attention. This paper presents an approach for enhancing the static voltage stability margin and reducing the power losses of the system with voltage security-constrained optimal power flow (VSC-OPF) that is based on static line voltage stability indices. The control approaches incorporate the voltage stability criteria into the conventional OPF. The minimization of the summation of fast voltage stability index (FVSI), line stability index (Lmn), and line voltage stability index (LVSI) is used as the objective functions. The performance and effectiveness of the proposed control approaches are evaluated on the standard IEEE 30-bus, 57-bus, and 118-bus test systems under normal and contingency conditions. The comparison analysis is carried out with different cases including minimization of generation cost. The proposed control approaches indicate the promising results and offer efficient countermeasures against the voltage instability of the system.

“…Reactive power market is usually separated from real power, and an independent market is implemented for it. [2][3][4] In this model, the output of the active power market is used as the input of this market. In previous studies, [5][6][7][8][9] by considering a combined objective function, a framework has been presented for optimization in all active and reactive power costs.…”

“…The pricing model refers to the allocation of reactive power costs for different participants. In previous studies, 2,10,[19][20][21][22] the pricing model based on the capacity curve of power plants has been used. In Ahmadi and Foroud, 23 nodal pricing scheme of reactive power is presented to improve this market.…”

Summary In this paper, 2 new reactive power market structures are presented. Active power flow by itself causes active and reactive losses. Considering such losses in the reactive power market without paying any costs is the main purpose of this paper. Therefore, this study attempts to improve the reactive power market and promote fair competition in reactive power generation by improving the market structure. The total payment by independent system operator will be reduced in these new structures. By extension, in this work, the cost payment function of synchronous generators is modified. To simulate and describe the proposed method in the implementation of the reactive power market, the Cigre 32‐bus test system is applied.

SUMMARY The significance and influence of bilateral component on optimal dispatch of mixed pool‐bilateral electricity market is the major issue to be examined for trade‐off between pool and pre‐specified bilateral transactions. This paper proposes single part optimal dispatch model that dispatches pool in coordination with privately negotiated bilateral transactions while minimizing cost of generation, accounting power balance equality constraints and inequality constraints. The critically loaded transmission line is identified, and when Unified Power Flow Controller (UPFC) is placed in it, optimal dispatch solution gets modified because of incorporation of UPFC parameters in the developed formulation. The methodology of multilayer perceptron network is adopted in this work with inputs to the neural network as percentage of bilateral component and status of UPFC for online evaluation of generation cost and incremental cost. The network is trained with back propagation training algorithm, and for IEEE 30 and IEEE 118 bus systems, it is established that Levenberg–Marquardt algorithm outperforms other algorithms in terms of accuracy.
