This paper presents the optimal power flow solution using Multi-Population based Modified Jaya (MPMJ) algorithm with Centre-Node Unified Power flow controller (C-UPFC) FACTS device. The C-UPFC is the current and advanced FACTS device to control the flow of active power and voltage magnitude at the line and bus. The C-UPFC is the basic derivative of the original UPFC device. Still, in the C-UPFC, this device connection is inserted in series with the transmission line and connected at the transmission line's midpoint. Therefore, The C-UPFC can independently regulate active and reactive power flows at both line ends and AC voltage magnitude at line midpoint. The optimal location of the C-UPFC device in the transmission line is determined by the Analytical Hierarchy Process (AHP) method by considering the objective functions given by priority order values. Therefore, the proposed MPMJ optimization algorithm applied with C-UPFC for optimal values of total fuel cost of generation, real power loss, the total voltage deviation, and the sum of squared voltage stability index on the standard IEEE-57 bus test system. The results obtained by the proposed MPMJ algorithm are better solutions effectively in the presence of C-UPFC device and is compared with the recent algorithm reported in the literature.
In this paper, exergy, exergoeconomic, and exergy cost sensitivity analyses of a cogeneration steam power plant cycle and a parametric study were carried out based on the exergy cost theory. The mathematical models were developed and presented regarding mass, energy, exergy, and economy. The thermodynamic properties and research analyses are done by employing the THERMAX, EXCEL and MathWorks software packages. The analyses leads to have valuable economic status benchmarks. The exergoeconomic factor, total cost of exergy loss, and unit cost of steam and cost of work were determined. The parametric study has been conducted, considering the effects of the annual working number of hours, interest rate, boiler maximum temperature, and environmental temperature. The exergoeconomic factor, total cost, unit costs of work and steam, rise with the escalation in the interest rate, while they drop with the rise in the annual working number of hours. The exergoeconomic factor and total cost are 0.5 and 9,000 $/h, respectively, for the considered normal operating status, while the unit costs of work and steam are 0.025 $/kWh and 0.035 $/kWh, respectively, for an interest rate of 14%. The achieved present results could lead site engineers, operators, and management to effectively establish an upgrade for the energy-related cycle performance.
Present day complex power system network especially power transmission is being operated under highly stressed condition due to continuous increase in electric power demand day by day in various sectors such as industrial, commercial and domestic etc. As long as load increases, the reactive power demand also increases abruptly. The main objective of the present research paper is to develop a strange way of analyzing the power system conditions by locating various FACTS devices such as STATCOM, SSSC and UPFC which improves voltage profile and minimize network losses. FACTS devices with suitable placement will meet the required reactive power demand of the complex and stressed power transmission system. In this paper the placement of FACTS devices using GA, PSO and HGAPSO heuristic techniques are introduced and the results are compared on IEEE 30 bus test system in a MATLAB environment. The HGAPSO heuristic technique gives effective placement than GA and PSO heuristic techniques are presented in this paper
This paper explores the design of load frequency controller for a multi area (two area) autonomous hybrid power system in which Distributed Generation (DG) resources are integrated. A novel controller such as 2DOFPID controller is established as a secondary controller. The controller gains are to be tuned with most popular meta-heuristic swarm intelligent technique named as Salp swarm alogrithm. The simulation results alleviates the efficacy and superiority of Salp Swarm Algorithm (SSA) being compared with other soft computing techniques such as Grasshopper optimization algorithm (GOA), Ant lion optimizer (ALO) and Particle swarm optimization (PSO) carried out under five different categories of load uncertainties.
This paper deals with a wind energy conversion system connected with grid. In this system rotor side and grid side converters are used to cope with reactive powers generated and to get the balanced output at the load side. A very effective control technique has been developed based on pulse width modulation to make the line voltages at the point of common coupling. Various filters have been used in this system and according to different filter parameters and design, the total harmonic distortion (THD) has been compared and calculated accordingly.
