    Extracting Maximum Power from Photovoltaic System using MPPT Techniques
    (International Journal on Recent and Innovation Trends in Computing and Communication, 2016-10) Bodhle, Gulrez
    In this paper for control of photo-voltaic power by utilization of a boost converter using Maximum Power Point Tracking (MPPT) control mechanism is presented. The MPPT is responsible for extracting the maximum possible power from the photo-voltaic and feed it to the load via the boost converter which steps up the voltage to required magnitude. The main aim will be to The main aim will be to extract maximum power from the photo-voltaic so its necessary to continuously track maximum power point of the photo-voltaic module. The MPPT basically works on an algorithm. The algorithms are usually written in m files of MATLAB and utilized in simulation.

    Overview to Electrical Substation Automation Using SCADA
    (Proceeding of NCATM-2017, 2017-03-24) Qureshi, Tahoora
    Abstract—“Supervisory control and data acquisition (SCADA) system” is universally accepted means of control for electrical substation which involves continual real time monitoring applicable to generation, transmission and distribution systems. The heart of SCADA lies in the functioning of Remote Terminal Units (RTUs) which collects analog and status telemetry data from field devices and also communicates command signals to them. The inclusion of automation in electrical substation has resulted in a string of advantages including visibility of network operation, flexibility of controls, real time accurate and consistent data, statistical data archiving, faster fault identification, isolation and system restoration. Complex design of SCADA systems involve accurate matching of protocols and communication parameters between connecting devices. This paper aims at establishing a basic understanding of SCADA components, communication protocols and architectures, standards employed and the security risks involved in such systems. Keywords—SCADA, Electrical Substation Automation, Communication Protocols, SCADA standards Organisation, SCADA Architecture.

    Powerformer- A Discontinuous Innovation
    (International Research Journal of Engineering and Technology (IRJET, 2016-11) Amin, Shraddha; Hule, Shraddha
    This paper provides an overview of a technology that offers a direct connection to the power network without a step up transformer. Implementation of powerformer will bring a change in the present scenario of generation. It is also shown that powerformer can act as differential protection scheme for high voltage cable wound generator. Many other applications like stability control, controlling high voltage bus, are mentioned.

    Review On Quantitative feedback Theory (QFT) To Maintain Power System Stabilty.
    (International Journal of Advances in Science Engineering and Technology, 2014-01) Amin, Shraddha
    There are different practical methods which are used to maintain the power system stability but these systems are characterized by high uncertainty which makes it difficult to maintain good stability. In case of conventional methods, if plant parameter changes we cannot assure about the system performance hence it is necessary to design robust control for uncertain plant. Among the various strategies proposed to tackle this problem, Quantitative Feedback Theory (QFT) has proved its superiority.[6] QFT falls into the classical control category, and is a frequency domain design method. It is an alternative to other design methods such as root locus and H∞. From theory, through simulation, on a single machine, infinite bus system, it will be shown that the application of QFT to robust PSS design does indeed work.Other methods allow the designer to produce a design for single operating point and one has no idea how the design performs at the other operating points. QFT is a design method that allows the designer to choose a set of realistic operating points and to produce a design that includes those points.

    Review on secondary and tertiary control structures for Microgrid
    (International Journal of Computer Sciences and Engineering, 2018-03-30) Qureshi, Tahoora; Alvi, Rizwan
    Abstract— With the large scale integration of Distributed Energy Resources (DERs) into the existing power system, there has been a significant impact on the operation of distribution networks; the major impacts being power quality problem along with congestion and voltage regulation issues. This demands coordinated control approaches which allow Distributed Generation (DG) units to actively participate in voltage and frequency regulation. To realize the same, hierarchical control structures constituting the primary, secondary and tertiary control structures are implemented. These controllers are classified as the centralized or the decentralized type. Thus by employing droop controls or impedance based controls desirable outcomes such as power sharing, non linear load sharing and harmonic reduction is possible thanks to coordinated operation of secondary and tertiary control layers with primary or local layer. This paper aims at establishing a basic understanding of these control layers as applied to AC and DC microgrids along with detailed explanation of modified structures from the conventional control structures in a typical microgrid.

    Solar Thermal Power Technology
    (International Journal on Recent and Innovation Trends in Computing and Communication, 2016-12) Bodhle, Gulrez
    Generally energy is available in two forms i.e. non renewable and renewable energy sources. Several environmental issues are related with the use of conventional energy sources like coal, petroleum and natural gas and different type of advantages or benefits offered by non conventional energy sources like solar, wind and small hydro included. Solar technology from history point of view is very old i.e. from 7th century B.C. to today. But in recent years the attention is more focused on solar energy for generate electricity. Solar energy help us to reduce the use of fossil fuel. Solar technology is a pollution free technology, so this technology is called by green technology. Solar energy can be used in two ways one of which is solar photovoltaic and another one is solar thermal and this paper is based on the review of solar thermal energy.
