  • volt var control algorithm for modern Distribution Management System
    IEEE Transactions on Power Systems, 1995
    Co-Authors: Ilya Roytelman, B.k. Wee, R.l. Lugtu
    Abstract:

    In this paper, a centralized volt/VAr control (VVC) algorithm for a Distribution Management System is presented. The algorithm is based on the oriented discrete coordinate descent method and takes into account all the optimization objectives of interest in Distribution System analysis: minimum power loss, power demand or the number of control steps to keep the System within constraints. Although the optimization method used belongs to the traditional class of combinatorial integer programming, the algorithm provides good speed for real-time application. Numerical examples illustrate how well the VVC algorithm works for the different types of objective functions and it's advantages in comparison with other possible optimization strategies. >

  • Distribution Management System dms integrated voltage var control
    Smart Grid Handbook, 2016
    Co-Authors: Seongchul Kwon
    Abstract:

    In pursue of low carbon society, distributed generators, including renewable energy resources such as solar photovoltaic, wind turbine, and battery energy Systems, have been interconnected to Distribution networks dramatically in recent years. In spite of lots of advantages of distributed generators, they also cause the voltage and protection coordination problem in Distribution network. To solve voltage problem in Distribution network, many research and demonstration projects have been conducted in decades. In this chapter, DMS (Distribution Management System) integrated VVC (voltage-VAR control) is summarized. Voltage variation problems in the Distribution networks due to distributed generators are introduced and voltage control devices used in Distribution network are reviewed. Later, two VVC methods to solve the voltage problems in Distribution network using voltage control devices are described. One is the decentralized approach using local controller for DG (distributed generator) or SVR (step voltage regulator), which control locally the voltage in the active way with additional information measurement. The other is VVO (voltage-VAR optimization) application, which resides and executes in real time in the DMS, optimizes the voltage profiles in Distribution network to solve the violation, and reduces the loss using control resources including OLTC (on-load tap changer), SVR, and distributed generators. Keywords: Distribution Management System (DMS); distributed generator; linear programming; Distribution automation System; VVO (voltage-VAR-optimization); voltage VAR control; optimal power flow (OPF)

  • The Development and Empirical Evaluation of the Korean Smart Distribution Management System
    Energies, 2014
    Co-Authors: Sang-yun Yun, Seongchul Kwon, Chul-min Chu, Il-keun Song, Joon Ho Choi
    Abstract:

    This paper introduces the development and actual test results of the Korean Smart Distribution Management System (KSDMS). The KSDMS has been designed and developed to cope with the lack of interconnection capability of the Dispersed Energy Resource (DER), to provide standardization and compatibility, and to implement automatic processing of service restoration, in the existing Distribution Automation System (DAS) in Korea. First, real-time System analysis and control application programs were developed, to solve the problems of the existing DAS; and the Distribution Management System (DMS) platform was developed, to run the developed application programs. Second, international standard-based communication, platform, and database structures were adopted, for standardization and compatibility. Third, a platform and application program functions were developed to process faults automatically; and a communication device and an intelligent electronic device (IED) were developed to automate fault restoration, through communication between devices. The KSDMS was evaluated by three tests: unit function test, platform and application program integration test, and empirical test. The first two were conducted on both small and large demonstration Systems. The empirical test was performed at the Power Testing Center (PTC) in Gochang, and on a real System, at the Korea Electric Power Corporation (KEPCO), on Jeju Island. The test results verified that the KSDMS can actively resolve the problems of the existing DAS.

  • A protection coordination estimation of Distribution network for smart Distribution Management System
    CIRED 2012 Workshop: Integration of Renewables into the Distribution Grid, 2012
    Co-Authors: Cheol-min Chu, Seongchul Kwon, Yun-sang Yuri, Il-keun Song
    Abstract:

    The smart grid offers new opportunities to improve the efficiency of operating and controlling Distribution Systems through the accurate information of the realtime situation of the network. And also, it is possible to automatically protect the network by using the communication infrastructure. The Korean Smart Distribution Management System (KSDMS) project launched at 2009 to achieve advanced Distribution operation for potential smart grid Systems in Korea. The KSDMS allows the optimization for operating and controlling the network, whose circumstance is hourly changed by the energy supply(depending on Distributed Generator(DG)) and consumption(depending on Load), by using the various analysis and control software. And also, in KSDMS, the energy security is highly considered by using the protection estimation method which automatically changes the setting value of protection coordination under the circumstance. In this paper, an adoptive algorithm for change and estimation of the protection coordination setting is proposed, and the protection coordination scheme designed in KSDMS is briefly introduced.

  • a vendor independent Distribution Management System development project considering emra regulations in turkey
    IEEE PES Innovative Smart Grid Technologies Conference, 2015
    Co-Authors: Serdar Ozbuber, Mustafa Bagriyanik
    Abstract:

    This paper presents the implementation of a Vendor Independent Distribution Management System (VI-DMS) considering EMRA Regulations in Turkey. The local challenges and expectations for a Distribution Management System were obtained by visiting several Distribution companies (DC) in Turkey. Priorities we identified are; enhancing Distribution networks to improve monitoring capabilities, identifying and reducing the losses and theft, managing grids more effectively to improve reliability, efficiency and quality while reducing costs. DC's also willing to incorporate smart grids concept and standards in their network. Consequently, a standards based new approach is derived and developed. It is vendor independent Distribution Management System (VI-DMS) to be the main platform for enabling the conversion of conventional Distribution networks to the SGs and for facilitating the integration of existing components with each other and also with emerging technologies from different suppliers. In this paper, a scheme of the proposed VI-DMS architecture is also presented.
