The proposed design topology has numerous desirable features such as better utilization of the photovoltaic array, low cost, compact size, simpler control and higher efficiency. For switching of inverter power circuit, we used a combination of sinusoidal pulse width modulation (SPWM) and square wave signal under grid synchronization condition. Moreover, to control SPWM duty cycle and to regulate the inverter's instantaneous ac output current, a closed-loop SPWM control scheme is employed to stabilize the output as fast as possible. The design and analysis of the inverter control circuit and grid synchronization methods are portrayed in detail. The proposed design is mathematically modeled which is simulated in PSIM. Finally, the simulation results are presented to verify the viability of the proposed single-stage three-switch buck-boost inverter for grid-connected photovoltaic application and confirmed the capability of the inverter to feed a sinusoidal current to the utility grid at a wide range of input photovoltaic dc voltage.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130920622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power system configuration is impacted by factors such as amount of power required, type of orbit, duration of the mission, and physical constraints of mass volume. The major functions of Power system encompasses power generation, energy storage and power processing. The organization of control and management circuits to carry out these functionalities is termed as Power Control and Management (PCM). The power system functionality is complex in nature with different functional elements working under different operating conditions. Estimation of composite efficiency is one of the vital parameter for selection of an optimum configuration in achieving the desired mission goal. Intuitive methods are generally used for finding out a suitable configuration with its associated elements. However availability of elemental efficiency models facilitate the bench marking of different options. Hence, a comprehensive methodology to estimate major loss factors has been formulated. The overall efficiency of power system configuration is evaluated based on the series parallel connection of modeled sub system elements.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115975257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cost of electricity from the PV array is more expensive than the electricity from the other non- renewable sources. So, it is necessary to operate the PV system at maximum efficiency by tracking its maximum power point at any weather conditions [1]. Boost converter increases output voltage of the solar panel and converter output voltage depends upon the duty cycle of the MOSFET present in the boost converter. The change in the duty cycle is done by Fuzzy logic controller by sensing the power output of the solar panel. The proposed controller is aimed at adjusting the duty cycle of the DC-DC converter switch to track the maximum power of a solar cell array. MATLAB/Simulink is used to develop and design the PV array system equipped with the proposed MPPT controller using fuzzy logic [2][3]. The results show that the proposed controller is able to track the MPP in a shorter time with less fluctuation. The complete hardware setup with fuzzy logic controller is implemented and the results are observed and compared with the system without MPPT (Fuzzy logic controller).","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131097150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this proposed logic maximum amount of energy is extracted from the renewable energy resources depend on their availability. The combination of suggested switching logic and circuit configuration allows the two renewable energy resources, to supply the load individually or simultaneously based on the availability. The fast operation and reliability of DSP controller is utilized to increase the efficiency of the proposed system at the most.

Each area of the systems is equipped with single reheat turbine and has a Generation Rate Constraint (GRC) of 3% per minute. System dynamics has been obtained by considering 1% step load perturbation (SLP) in area 1. Performances of several classical controllers such as Integral (I), Proportional-Integral (PI), Integral-Derivative (ID), Proportional-Integral-Derivative (PID) and Integral-Double Derivative (IDD) has been evaluated and compared in the two area system. Bacteria Foraging (BF) technique has been used for optimization of controller gains. Investigations reveal that IDD controller provides better dynamic than the others. Thyristor-controlled Phase Shifter (TCPS) in tie-line has been used for damping the oscillations in the frequency and tie power deviations. TCPS is applied in both systems with IDD controller in the secondary loop. An appropriate tie-line for use of TCPS in series has been selected. Investigations reveal that using TCPS the oscillations and peak deviations in the responses can be reduced. Simultaneous optimization of Governor Speed Regulation parameter (Ri) for primary control loop and gains IDD controller (KIi, KDi) for the three unequal area system with IDD controller using BF technique provides higher values of Ri, thereby leading to economic and convenient realization of Governors. Sensitivity analysis has been performed to see the robustness of KIi, KDi and Ri obtained at nominal condition on the three area system with TCPS with wide change in loading conditions, Inertia constant(H) and magnitude and location of SLP and established that they are robust.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126631175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Voltage instability is a major problem that occurs due to deficit of reactive power at load buses in power system under increased loading or during contingencies. Voltage stability of a power system can be improved using Flexible AC transmission systems (FACTS) controllers like thyristor controlled series compensator (TCSC), static var compensator etc. Like other FACTS controllers, TCSC is a costly device involving huge investment. Hence, it is important to find its optimal location and its size, in order to improve voltage stability in a power system. In this paper, Particle Swarm Optimization with time varying acceleration coefficients (PSO-TVAC) has been proposed to find out the optimal location and size of TCSC for voltage stability improvement of a power system. This paper considers line stability index (LSI) for determining the optimal location of TCSC. Line stability index provides information about the stability condition of a power system and its proximity to voltage collapse. The effectiveness of proposed method has been demonstrated on a standard IEEE 30-bus system.","PeriodicalId":352711,"journal":{"name":"2014 POWER AND ENERGY SYSTEMS: TOWARDS SUSTAINABLE ENERGY","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127147397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
