Study on microgrid operation control and black start

2011 4th International Conference on Electric Utility Deregulation and Restructuring and Power Technologies (DRPT), 2011
Along with the increasing distributed generation (DG) technologies, the development of the power market and the shock of serious blackout, more and more people focus research on microgrid (MG) technologies. Firstly under normal operating conditions, MG operation control is the most important problem for MG stable work.

A Case-Based Reasoning System for Black-start

2006 International Conference on Power System Technology, 2006
the basic strategy of case-based reasoning (CBR) is retrieving the most relevant cases and adapting them to fit new situation, and solutions would be stored for future reuse. A conceptual framework for a CBR system to scheme black-start plan is presented.

Evaluation of Restoration Sequence of DG in Black-Start

Applied Mechanics and Materials, 2015
With the rapid expansion of the grid, how to solve the security and stability of power system has become a hot problem. As a power system after a serious accident the necessary security measures, black-start programs are expected to play an extremely important role in reducing the loss of equipment and user outage and decreasing the outage time.

An improved method for black start of hybrid microgrids

2017 36th Chinese Control Conference (CCC), 2017
Microgrid(MG) system black start restoration is an integral part in providing power to traditional grid and stable operation of MG. Aiming at choosing the black start power supply, information entropy theory is used in assessment of distributed generation(DG)'s black start capacity.

Governor control study at the time of a black start

IEEE Power Engineering Society General Meeting, 2004., 2004
The power system of Kyushu Electric Power Company Inc. (KEPCO), whose size is about 19 GW, belongs to the Western Japan interconnected power system of 110 GW. Its grid system is made up of 500 and 220 kV transmission lines in a looped configuration. When the KEPCO power system falls into a blackout, it will be restored from a small-scale power system ...

A framework for black start and power system restoration

2000 Canadian Conference on Electrical and Computer Engineering. Conference Proceedings. Navigating to a New Era (Cat. No.00TH8492), 2002
This paper introduces the concept of a new framework for power system restoration. Its objective is to minimize the large number of time-domain simulations that is usually necessary in order to find a suitable restoration sequence. The new method is based on rules that deal with specific problems encountered during restoration and that are formulated ...

Optimization of Black-Start Scheme for Mitigating Overvoltage

2019 IEEE Innovative Smart Grid Technologies - Asia (ISGT Asia), 2019
This paper presents an optimization model of black-start schemes. In the current black-start optimization process, overvoltage is not considered reasonably. Therefore this paper considers the factors such as transformer inrush current amplitude and line overvoltage amplitude in the process of black-start.

Analysis of Black Start Strategies for Microgrids with Renewable Distributed Generation

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
Microgrids with a high penetration of distributed generation (DG) in combination with energy storage systems (ESS), but also in combination with fuel-driven generation units (gensets) can be operated in on-grid mode, but also in off-grid mode (island operation). For grid restoration in island mode, a black start strategy is needed. This scientific work

A New Method of Black Start Based on VSC-HVDC

2010 International Conference on Computing, Control and Industrial Engineering, 2010
For a good Black-Start scheme, it is important to avoid inrush current and transient over voltage while starting-up other major power system equipments. In this paper, the advantages of VSC-HVDC as black start power are analyzed. Control Strategies of VSC-HVDC in different operating conditions are discussed.
