The design of proposed PID controller is considered with an objective function based on square error minimization to enhance the small signal stability of nonlinear power system for a wide range of operating conditions. Three benchmark power system models as single-machine infinite-bus (SMIB) power system, two-area four-machine ten-bus power system, and IEEE New England ten-machine thirty-nine-bus power system are considered to examine the effectiveness of the designed controller. The BA optimized PID based PSS (BA-PID-PSS) controller is applied to these benchmark systems, and the performance is compared with controllers reported in literature. The robustness is tested by considering eight plant conditions of each system, representing the wide range of operating conditions. It includes unlike loading conditions and system configurations to establish the superior performance with BA-PID-PSS over-the-counter controllers.

The proposed optimization of scaling factors of FPSS is considered with an objective function based on square error minimization to guarantee the stability of nonlinear models of test system using BA. The BA-optimized FPSS (BAFPSS) controller is applied to the standard IEEE tenmachine thirty-nine-bus test power system model in the decentralized manner, and the performance is compared with the robust fuzzy controller. The robustness is tested by considering four different models of the test power system with different fault locations to establish the superiority of the proposed BAFPSS over the FPSS.

Th... more A simultaneous study of load frequency control and automatic voltage regulation is considered. The singlearea and two-area power systems have been considered with a combined model of AGC and AVR for analysis of frequency and voltage deviation. The primary aspect of the design is to keep real power control as to preserve frequency of the system in a prescribed limit. Reactive power control is used to keep the voltage magnitude of synchronous generator at a tolerable limit. The transients produced in dynamic responses are controlled using intelligent and soft-computing technique. The fuzzy logic controller and particle swarm optimization based PID controllers are considered. The steady state error and settling time of the dynamic responses are observed and found to be reduced very effectively. The frequency and terminal voltage results of a single-area power system with proposed PSO-PID controller is compared to the responses of system with controllers presented in literature and found to be more effective. The comparison of fuzzy logic controller with PSO-PID is done by observing the nature of two-area responses. The result obtained by soft computing algorithm and intelligent controller is analyzed on the basis of settling-time, undershoot and ISE Error.

The input signals to the controller are considered as speed deviation and acceleration. The application of IT2 FLC as PSS (IT2 FPSS) is considered to improve small signal stability of power system. It is considered for three different benchmark systems such as single-machine infinite-bus (SMIB), two-area four-machine and IEEE ten-machine thirty nine-bus power system. The performance with IT2 FPSS is compared against the performance of the power system without PSS, with conventional PSS (CPSS) and with fuzzy PSS (FPSS). The application of IT2 FPSS is extended to two-area four-machine ten-bus and IEEE New England ten-machine thirty nine-bus power system and speed response comparison is carried out with FPSS. The superiority of performance with IT2 FPSS over type-1 FPSS is validated in terms of ITAE, IAE and ISE.

The analysis of higher order models is complex, and time consuming. The application of model order reduction is necessitated to reduce the system with its core properties. The analysis of a low order system is easy, and fast process. The higher order systems are reduced using differentiation method and the results are compared with original and the reduced systems in literature. The performance comparison of the proposed reduced order model and original as well as systems in literature have been considered in terms of settling time, rise time, peak and peak time. The application of proposed differentiation method is applied to discrete system and found equally good to retain the stability in reduced order model.

The main work of load frequency control is to regulate the power output of the generator within a specified area with respect to change in the system frequency and tie-line power; such as to maintain the scheduled system frequency and power interchange with other areas in a prescribe limits. In this paper, study of LFC system for single area and double area non-reheat thermal system is carried out. Fuzzy logic controller is used for controlling the frequency and tie-line power deviation. The robustness of the fuzzy logic controller is seen for different loading condition.

In the power system it is require maintaining the frequency and voltage in a tolerable limit. but due to sudden load variation it is difficult to maintain them in a prescribe limit; so it is necessary to take some control action for this automatic generation control for frequency and automatic voltage regulator for voltage is used. The AGC is used for balancing system generation against system load and losses. Further the role of the AVR is used to maintain terminal voltage of the synchronous generator in order to keep the bus bar voltage in a tolerable limit. By using MATLAB software of version R2010 a, the analysis of frequency deviation and voltage variation with time is done for a single area system. By using the controller it can be seen that the deviation of frequency response and voltage is minimized. In this paper the comparison of a conventional controller like PI, PID is done with fuzzy logic controller, and we find that fuzzy controller is better than the conventional controller.

The design of proposed PID controller is considered with an objective function based on eigenvalue shifting to guarantee the stability of nonlinear plant for a wide range of conditions using HSA. The HSA optimized PIDPSS (HSPIDPSS) controller is applied to the standard IEEE ten-machine thirty nine-bus test power system model in decentralized manner and the performance is compared with a robust fuzzy controller. The robustness is tested by considering four plant conditions with change of active power, active load and faults at different buses of the power system to establish, the superior performance with HSPIDPSS over the FPSS.

The FLC rule base is generally based on empirical control rules. In this method, the fuzzy system with a large number of fuzzy rules is compressed to a fuzzy system with a reduced number of rules by removing the redundant and inconsistent rules from the rule base which doesn't affect the performance of the fuzzy logic controller. The FLC based PSS has two input signals as speed deviation and derivative of speed deviation with an appropriate number of linguistic variables. The number of compressed rules in the rule base through the proposed dominant rule algorithm is reduced to a number as low in the number of selected linguistic variables to represent input and output signals. The application of the FLC with compressed rules as a power system stabilizer (CR-FPSS) is investigated by simulation studies on a single-machine infinite-bus system (SMIB). The superior performance of this compressed rule based fuzzy PSS (CR-FPSS) as compared to conventional PSS and proves the better efficiency of this new CR-FPSS. The reduced CPU computational time and storage space as compared to the fuzzy power system stabilizer (FPSS), proves its applicability in control.

The single machine infinite bus (SM IB) system is considered for evaluation and implementation of IT2 FLC as PSS. The input signals to the controller are considered as speed deviation & acceleration. The evaluation of the controller is considered with 20 separate types of membership functions (M Fs) and treated as IT2 FPSS on SM IB system to evaluate the performance of each. The performance of these M Fs is evaluated graphically as well as in terms of ISE, IAE & ITAE as the performance index. The better suitable MF as FPSS is decided out of considered 20 M Fs. The selected M F based IT2 FPSS is tested for small signal performance analysis of an SM IB system with wide operating conditions of a power system. The performance with IT2 FPSS is compared to the performance of the power system without PSS & with conventional P SS.

The complexity often makes it difficult to obtain a good understanding of the behavior of a system. The exact analysis of most of high order system is both tedious and costly; it poses a great challenge to both system analyst and control engineer. The preliminary design and optimization of such systems can often be accomplished with greater ease if a low order linear model is derived which provides a good approximation to the system. Hence, methods have been developed here to obtain simplified models of the systems by using different reduction techniques.
