Fibonacci series-based local search in spider monkey optimisation for transmission expansion planning

Abstract: The power system is a complex interconnected network which consists of four components: generation, distribution, transmission, and load. The loads may be varying in nature. For supplying these loads, with an aim of minimum losses in transmission and distribution, the additional transmission lines are required to be added for expansion. To find out the optimum locations of these additional lines are a complex and challenging task. Swarm intelligence motivated algorithms have been proved to be efficient to deal this type of optimisation problem. Therefore, this work applies a recent swarm intelligence motivated algorithm namely, spider monkey optimisation (SMO) to identify the optimum locations for the additional lines in the system. Further, to augment the solution search capacity of SMO algorithm, a Fibonacci series-based local search (FLS) is proposed and incorporated with SMO. The modified SMO is named as Fibonacci inspired spider monkey optimisation algorithm (FSMO). The authenticity of the suggested FSMO is analysed through statistical analysis over 20 benchmark functions. Further, both the algorithms, FSMO and SMO are applied to solve the transmission expansion planning (TEP) problem for IEEE-24 bus system. The reported results are judged against other state-of-art algorithms for solving TEP issues.

Design and performance analysis of PID based controller for SMIB power system using Firefly algorithm

Abstract: This article presents the design of a proportional, derivative and integral (PID) based controller using a new meta-heuristic Firefly algorithm (FFA) to optimize the parameters. The design of proposed PID controller using FFA is considered with an objective function based on minimization of square of error signal to guarantee the stability of a nonlinear power system for a wide range of conditions. The FFA optimized PID controller (FFA-PID) is applied to the standard single-machine infinite-bus (SMIB) power system model, and the performance were compared with previously established Ant Bee Colony based PID controller (ABC-PID), and Many Optimizing Liaisons based PID controller (MOL-PID). The performance is compared with simulation of the nonlinear power system for eight plant conditions, and superiority is validated using performance indices. Moreover, the superiority of the proposed controller is validated by plot of eigenvalue in left half of s-plane and verified over 231 plants, including very heavy operating conditions.

Modeling and Simulation of gird connected hybrid power system integrated with solar PV/Wind and controlled by Voltage Regulator

Abstract: Due to hike in price of conventional source of energy we attentive toward non -conventional source of energy. This paper with present of a hybrid solar-wind energy system with gird connected. Hybrid solar-wind system consist wind, solar source and ac loads. In solar dc output system is raised by boost converter. MPPT technique is used to maximize the output of solar system. The wind subsystem is made of a permanent magnet synchronous generator and rectifier, boost converter for maximum output. Voltage regulator is used for controlling the hybrid solar & wind system. Modeling of hybrid PV and wind turbine which is controlled by voltage regulator is explained. To increase reliability & reduce reliance on one single source we connected these two systems.

Distributed generation integration optimization using fuzzy logic controller

Abstract: Distributed generators (DGs) are connected near load centers and integrated to grid for optimum power system operations. The challenging task for integration of DGs is the proper size and location, due to random character of generation and energy consumption. The objective of the research is to provide the proper size and location of DGs to optimize the voltage profile and reduction in active and reactive power losses. Optimization of distributed generators is performed through fuzzy logic controllers at Ramchandrapura 33/11 kV, 69 bus radial distribution substation, Kota, India. Fuzzy logic controller provides possible solution on selection of distributed generators on the basis of voltage profile of the bus and the impedance of the branch connected DGs at consumer’s end. Forward or backward sweep methodology is used to optimize the load flow analysis for calculation of real and reactive power losses and voltage profile with and without implementation of distributed generators. Proposed approach provides a possible solution for efficient integration of DGs.
