A sensitivity-based approach for optimal location of multi-converter unified power flow controller considering its impact on generation and wheeling costs
The optimal location of Flexible AC Transmission Systems (FACTS) controllers is important due to their high cost. When a FACTS controller uses some converters, its cost becomes very high. A multi-converter unified power flow controller, also known as Generalised Unified Power Flow Controller (GUPFC) can effectively control the power system parameters such as bus voltage and real and reactive ...

Multi-objective optimal placement with multi-type FACTS devices by hybrid TS/SA approach
In this paper, a hybrid Tabu Search and Simulated Annealing (TS/SA) approach is proposed to find the optimal placement of multi-type FACTS devices to simultaneously minimise the total generator fuel cost and violation function. The problem is decomposed into the Multi-Objective Optimal Placement (MOOP) of multi-type FACTS devices subproblem that is searched by the hybrid TS/SA approach and the ...

Management of power transactions using particle swarm optimisation
In this paper, a particle swarm optimisation (PSO) technique has been proposed for congestion management in different market structures comprising pool model, mix of pool and bilateral contracts by change in generation, such that the line flow which violate the limit are alleviated and the system security is maintained. The first stage describes a technique for selection of suitable participating ...

Principal component analysis–based real coded genetic algorithm for optimal reactive power dispatch
This paper presents a new solution method for optimal reactive power dispatch (ORPD) problem based on principal component analysis (PCA). In heavily loaded power system, security, reliability and economy are some unavoidable concerns. Therefore, ORPD becomes an essential tool to achieve these goals. It is a highly non–linear constrained optimisation problem. A PCA–based real coded genetic ...

OPF with FACTS devices in interconnected power systems using fuzzy stochastic algorithms
This paper presents two new computationally efficient improved stochastic algorithms for solving optimal power flow (OPF) in interconnected power systems with FACTS devices. These algorithms are based on the combined application of fuzzy logic strategy incorporated in both evolutionary programming (EP) and tabu search (TS) algorithms, hence named as fuzzy mutated evolutionary programming (FMEP) ...

Mathematical optimisation techniques applied to power system operation and planning
Nowadays, power system operation becomes more complex because of the critical operating conditions resulting from the requirements of a market-driven operation. In this context, efficient methods for optimisation of power system operation and planning become critical to satisfy the operational (technical), financial and economic demands. Therefore, the detailed analysis of modern optimisation ...

Rerating Pipeline Pumps
Pipeline operators transport billions of gallons of oil every year, and they are constantly looking at ways of improving efficiency and reducing costs. Depending on changing network demands, this might require managing an increase or decrease in flow rate in the pipeline, a change in pressure, or a pump upgrade to more efficient technology. Throughout the life of a pipeline, the process ...

An efficient artificial immune algorithm for power system reliability optimisation
Many systems as mechanical electrical or telecommunication are implemented by using a set of interconnected subsystems. While the design of the overall system may often be fixed, individual subsystems may be implemented differently. A designer needs to either achieve highest reliability while minimising the total cost, or maximise the reliability while using only the available budget. ...

Ultrasonic removal of cyanobacteria
This paper studies the ultrasonic removal of cyanobacteria. The results show that ultrasound is an effective way to reduce the water turbidity and to damage chlorophyll a, the antenna complex. Furthermore, 55% of the cyanobacteria were removed after 5 min treatment and no rebound was observed after 3 h. The ultrasonic cyanobacteria removal followed a pseudo first-order reaction and the rate ...

Validation of computational non-Newtonian fluid model for membrane bioreactor
Membrane bioreactor (MBR) systems are often considered as the wastewater treatment method of the future due to their high effluent quality. One of the main problems with such systems is a relative large energy consumption, compared to conventional activated sludge (CAS) systems, which has led to further research in this specific area. A powerful tool for optimizing MBR-systems is ...

PSO embedded online adaptive self-tuning UPFC shunt converter control
The dynamic performance of a power system can be improved by using additional signals in a unified power flow controller (UPFC) circuits. Self-tuning adaptive control of phase angle of shunt converter for stabilisation is considered in this article. From the input-output data record, a linear plant model of the UPFC is identified through a least square regressive algorithm. Stabilising control is ...
