“…every 5 minutes in Ontario). Thus, decoupling the OPF problem and handling reactive power dispatch separately [15], [25], [26], helps alleviate market power and price volatility which may come into play if reactive power dispatch is handled in the same time-frame as that of real power market clearing [12].…”

“…Reactive power procurement is essentially a long-term issue, where the ISO signs seasonal contracts with possible service providers that would best suit its needs and constraints in the given season [13], [14]. Reactive power dispatch, on the other hand, corresponds to the short-term allocation of reactive power generation required from already contracted suppliers based on "real-time" operating conditions [15], [16]. The issues associated with the first level of the proposed framework, i.e.…”

“…The ISO's problem is to determine the optimal reactive power schedule for all providers based on a given objective that depends on system operating criteria. Different objective functions can be used by the ISO, besides the traditional To appear in IET Generation, Transmission and Distribution, special issue on "Markets and Economics in Power Systems" 4 transmission loss minimization, such as minimization of reactive power cost [15], [16], [18], or minimization of deviations from contracted transactions [19]. Any of the aforementioned objectives can be adopted, but since some of them are of a conflicting nature, the ISO needs to choose a criterion that best suits the market structure.…”

“…The real and reactive power prices are decomposed into the generation cost and the transmission losses [50,51]. The optimal reactive power dispatch, in terms of optimal allocation and generation of reactive power required by the load centers, is based on the real-time operating conditions [52,53]. The generation companies' strategy in managing output can be modeled as a bi-level optimization problem [54].…”

This paper presents a novel optimization algorithm for the multi-area multi-fuel economic-emission dispatch problem and total power loss objective. The proposed method uses the uniform distribution to determine the control parameters and employs a two-stage initialization process. This enables various objectives to be optimized under practical constraints and device limits. We formulate a realistic generation cost that includes the cost of reactive power generation, shunt power injections, and total power losses, along with the conventional active power generation cost. A novel objective based on the concept of multi-fuel emissions makes the problem more realistic, and a generalized unified power flow controller (GUPFC) is considered. A detailed power injection model is developed for a GUPFC with two series converters, including switching losses of converters. A nondominated sorting methodology and particle swarm optimization algorithm are then used to solve the multi-objective problem on the standard IEEE-30 bus and real-time Indian-124 bus test systems.Keywords GUPFC power injection model · Multi-fuel active power cost · Multi-fuel reactive power cost · Multi-fuel emissions · GUPFC installation cost · NSUDTPSO

“…If generator produces more reactive power with respect to minimum value, it will be counted for system security and the power producers should expect remuneration from the system operator. On the other hand if generator is lagging behind the minimum reactive power generation, it has to take support of system security to sell active power in worth of paying money [3][4]. Thus in the deregulatory power environment this remuneration concept via system operators facilitates competitive situation in terms of system voltage security.…”

Power system structure is undergoing through restructuring process since a decade. Everyday a bulk amount of power is generated, transmitted and distributed via transmission network. The active power or the real power generated from the generator needs the reactive power for supporting its own transmission. This reactive power generation has some minimum limit which if generator fails to produce it has to take support from system operator for smooth real power flow in worth of paying money. While the generator produces excess reactive power it can expect remuneration from the system operator. In deregulated power system minimal reactive power generation is considered as an important issue as cost is related to it. In this paper IEEE 14-bus test system is considered for solving the problem. As a solving tool a well known population based metaheuristics technique: particle swarm optimisation is chosen which tries to optimize the problem by controlling the generator bus voltage. The choice of the objective function and the mentioned optimisation technique is considered by through literature survey.Index Terms--Balanced voltage profile, minimal of reactive power generation, particle swarm optimisation, real power output.
