In this paper, the new hybrid particle swarm optimization (hybrid-PSO) based on particle swarm optimization (PSO), evolutionary programming (EP), and tabu search (TS) is developed. Hybrid-PSO is proposed to determine the optimal allocation of multi-type flexible AC transmission system (FACTS) controllers for simultaneously maximizing the power transfer capability of power transactions between g...

Proposed Probabilistic Load Flow (PLF) approach, based on the method of cumulants, is used for bus voltage security assessment. The work accurately estimates the unknown probability distribution and density function of the involved complex random variables (CRV’s). With the help of these distributions a fast and accurate contingency ranking for security assessment is made possible. The advantag...

In restructured power market, power producers and customers utilize the transmission network and try to maximize their benefits. Hence it is important to improve the static ATC for allowing more transaction in future without any transmission limit violation. This paper suggests the method for establishing bilateral/multilateral transaction based on the optimal generator selection and it’s shari...

Deregulation is the major trend in the electric power industry throughout the world. The main focus in deregulated system operation is to optimize the system welfare by introducing competition, mainly, among generators. The grid operator is required to know how the power offered by the generators is reaching the load; for which the power flow is to be traced along the lines. Tracing of electric...

In deregulated power systems, the transmission loss allocation plays a key role in planning and designing of the power system. In practice, these losses should be allocated to both generators and loads depending on the amount of contribution in the total power system losses. In this paper, a new methodology to optimally allocate the transmission losses to either generators or loads based on the...

The Analog and Mixed-Signal Boundary-Scan Standard (IEEE1149.4 hereafter referred as dot4) was developed to measure external discrete components in a mixed-signal Printed Circuit Assembly (PCA). This bus uses 4 of the same signals used today to support IEEE1149.1 compliant devices and systems. It uses two additional wires bus to perform analog monitoring and control. But testing a mixed-signal ...

This paper presents an attempt to explore the applicability of harmony search algorithm (HSA) to solve extremely challenging non-convex economic load dispatch (ELD) problem with transmission losses involving variations of consumer load patterns. The efficiency of the proposed approach HSA has been tested successfully on the standard 6-bus system, IEEE-14 bus system, and the IEEE-30 bus system w...

This paper proposes a Trust-Region Based Augmented Method (TRALM) to solve a combined Environmental and Economic Power Dispatch (EEPD) problem. The EEPD problem is a multi-objective problem with competing and non-commensurable objectives. The TRALM produces a set of non-dominated Pareto optimal solutions for the problem. Fuzzy set theory is employed to extract a compromise non-dominated sol...

This paper presents the application of Genetic algorithm (GA) to solve the economic load dispatch problem of the power system. The effectiveness of the proposed algorithm has been demonstrated on two different test systems considering the transmission losses. Test system-1 includes a three generator system and test system-2 includes an IEEE 30-bus system. The results of test system-1 are compar...
