Development of a methodology for assessing the adequacy of electric power systems

Global Energy Interconnection 2022年第5期5卷 543-550页

作者： Dmitry S.Krupenev Denis A.Boyarkin Dmitrii V.Iakubovskii Melentiev Energy systems Institute of Siberian Branch of the Russian Academy of Sciences Lermontov str.130Irkutsk664033Russia

This study presents the results of a research into the developing a methodology for assessing the adequacy of advanced electric power systems characterized by the integration of various innovative technologies,which complicates their analysis.The methodology development is aimed at solving two main problems:(1)increase the adequacy of modeling the processes that occur in the electric power system and (2)enhance the computational efficiency of the adequacy assessment methodology.This study proposes a new mathematical model to minimize the power shortage and enhance the adequacy of modeling the processes.The model considers quadratic power transmission losses and network coefficients.The computational efficiency of the adequacy assessment methodology is enhanced using efficient random-number generators to form the calculated states of electric power systems and machine learning methods to assess power shortages and other reliability characteristics in the calculated states.

关键词： electric power systems Adequacy power shortage minimization Pseudo-and quasi-random number generation Machine learning methods.

From interconnections of local electric power systems to Global Energy Interconnection

引用

Global Energy Interconnection 2018年第1期1卷 4-10页

作者： Nikolai Voropai Sergei Podkovalnikov Kirill Osintsev Melentiev Energy systems Institute SB RAS National Research University 'Moscow power Institute'

The interconnections of electric power systems are developed for the economic benefits and in order to increase the overall power supply reliability and quality level. Development of power industry shows the positive effects in operation of the country-wide electric power systems and international interconnections. Creation of World Energy System or, by the other words, Global Energy Interconnection is objective trend on the way of expansion of international and intercontinental electric power interconnections. Several important aspects of above mentioned problems are discussed in this paper.

NEWLY-DEVELOPED AND CHEAP NANOCRYSTALLINE Fe-Cu-Nb-Mo-Si-B ALLOYS FOR SWITCHING MODE power SUPPLY

引用

Acta Metallurgica Sinica(English Letters) 1997年第6期10卷 489-494页

作者： Zhang, Y.Z. Shanghai Iron and Steel Research Inst Shanghai China

The synthetical soft magnetic properties were reported for newly-developed nanocrystalline Fe73.5Cu1Nb0.9 Mo2.1Si13.5B9 and Fe73.5Cu1Nb0.5 Mo2.5Si13.5B9 alloys. The levels of high-frequency losses of the new alloys are P3/100k=612 and 670 kWm-3, P2/200k=880 and 973kWm-3, P2/500k=4300 and 4600 kWm-3, P0.5/1000k=860 and 920 kWm-3, respectively. They are significantly lower than those of the superior power Mn-Zn ferrite H7c4. The dependence of core loss on frequency and amplitude flux density has been analyzed. The practical applications of the new alloys to switching mode power supplies with the output power of 1 and 2kW were reported.

Towards a (More) Electronic Transmission and Distribution (eT&D)

引用

CES Transactions on electrical Machines and systems 2017年第1期1卷 15-25页

作者： Don Tan Damir Novosel IEEE NGAS Quanta ABB KEMA T&D US

The challenges and the path towards a(more)electronic transmission and distribution(eT&D)is presented in this paper.The challenges are first identified together with key stakeholders in the drive for grid modernization.A fundamental question is then asked about the investment priority.Six basic characteristics are reviewed,leading to the composition of structured microgrids as the basic functional cell of a modern grid.One example of fractal radial structure and one fractal meshed structure are presented.The likely evolution path is then proposed together with basic technology sets.Specific foundation technologies are discussed in detail,including adiabatic power conversion,3MC technology,medium voltage conversion,distribution-level electronic power transformer and FACTs hardware integration,and back-to-back converters as a universal interconnect element.The rapidly emerging on-wire sensing technology is also discussed.It is pointed out that the distribution-level large electronic power transformer will provide a key component to enable hybrid ac/dc grid flow control and ancillary support for a flexible electronic transmission and distribution(eT&D)systems.

关键词： All things grid connected electric power systems electronic transmission&distribution(eT&D) energy solutions flexible electronic transmission systems(FETS) grid modernization large electronic power transformers 3MC converters renewable energy.
