“…Although, much research on the reactive power market in a restructured power system, at the wholesale level, has been performed [16][17][18][19], in few works the potential of expansion of a reactive power market at the distribution level with DGs has been reported [3,20,21]. Additionally, the reactive power capability of DG has not been considered in the previous research on the VVC problem.…”

Abstract:One of the most significant control schemes in optimal operation of distribution networks is Volt/Var control (VVC). Owing to the radial structure of distribution systems and distribution lines with a small X/R ratio, the active power scheduling affects the VVC issue. A Distribution System Operator (DSO) procures its active and reactive power requirements from Distributed Generations (DGs) along with the wholesale electricity market. This paper proposes a new operational scheduling method based on a joint day-ahead active/reactive power market at the distribution level. To this end, based on the capability curve, a generic reactive power cost model for DGs is developed. The joint active/reactive power dispatch model presented in this paper motivates DGs to actively participate not only in the energy markets, but also in the VVC scheme through a competitive market. The proposed method which will be performed in an offline manner aims to optimally determine (i) the scheduled active and reactive power values of generation units; (ii) reactive power values of switched capacitor banks; and (iii) tap positions of transformers for the next day. The joint active/reactive power dispatch model for daily VVC is modeled in GAMS and solved with the DICOPT solver. Finally, the plausibility of the proposed scheduling framework is examined on a typical 22-bus distribution test network over a 24-h period.

“…Different reactive power payment structures can be used for synchronous generators (Bhattacharya, & Zhong, 2001;Hao, 2003;Hasanpour, Ghazi & Javidi, 2009). In (Hasanpour, Ghazi & Javidi, 2009) a quadratic reactive power cost curve has been proposed for a typical synchronous generator.…”

“…As it is described in (Hasanpour, Ghazi & Javidi, 2009), knowing active power cost curve of a generator, its capability curve and maximum amount of active and reactive power of that generator, these constant coefficients can be estimated accurately using a suitable interpolation technique. This equation can provide accurate results in reactive power market while it is very simple for implementation.…”

“…Different optimization problems are proposed in literature which most of them define the total reactive power payment as an important object of the optimization (Bhattacharya, & Zhong, 2001;Hao, 2003;Hasanpour, Ghazi, & Javidi, 2009). But, considering only reactive power cost may cause increasing total system energy loss which usually results in increasing total market payment.…”

In deregulated electricity markets, reactive power provision is one of the most important ancillary services which is vital for reliable and secure operation of the system. In all electricity markets, economic issues play an important role in market scheduling. This paper presents an algorithm to find optimal reactive power market schedule. The proposed algorithm seeks to minimize a novel three-component payment function which precisely considers economic issues in the market. Two first parts of this function are reactive power provision cost and transmission loss payment. Moreover, another important part of this payment function, which has not considered in the time of reactive power market clearing in literature, is transmission charge payment. As it is shown in simulation results, this term of the function can importantly impact on final reactive power market schedule and consequently on total market payment and final market schedule. Furthermore, due to significant impact of reactive power on system voltage stability, the algorithm tries to schedule reactive power market with an adequate voltage security margin. Sequential quadratic programming is employed to clear the algorithm which is a nonlinear constrained optimization problem. The proposed algorithm is applied on IEEE-24 bus test system with satisfactory results.
