About Power System Technology

Power System Technology

Power System Technology is a Chinese-language journal of power-system technology published in Beijing by the research system of the State Grid Corporation of China, with ISSN 1000-3673. Its Chinese title is Dianwang Jishu, which translates literally as 'power grid technology'. SCImago ranks it among China's leading energy journals, in the first quartile (Q1) for energy engineering and power technology, and its stated scope covers grid planning, grid operation, renewable-energy integration and electricity markets. It is one of the principal Chinese journals through which research on building and running China's power grid is published.

A Journal of the Power Grid Itself

Where some Chinese power journals concentrate on a single technique — automation, high voltage, protection — Power System Technology takes the grid as a whole for its subject. Its Chinese title, Dianwang Jishu, names the power network directly. Planning how a grid should grow, operating it safely and economically day to day, connecting new forms of generation to it, and trading electricity across it are the journal's documented concerns, and together they amount to the complete professional agenda of a grid industry.

The journal is published in Beijing within the research system of the State Grid Corporation of China, the company that operates most of China's transmission and distribution networks. SCImago-derived records name its publisher as Power System Technology Press. A journal rooted in the grid operator's own research establishment speaks with particular authority on operational questions, because its community includes the engineers who plan and run the actual network.

Bibliographic Record and Standing

The journal's ISSN is 1000-3673, recorded in journal databases alongside its publisher, Power System Technology Press, its country, China, and its subject areas of energy and engineering. Database coverage summaries record the journal as active across the 2000s and continuously in recent years. In SCImago's journal-value tables for China it stands near the very top of the energy-engineering and power-technology category, with a SCImago Journal Rank of 1.336 and Q1 standing in the 2025-based table, which credits it with 368 documents in that year.

Those figures place Power System Technology in the first rank of Chinese power journals by the standard bibliometric measures applied to Scopus data. A Q1 Chinese-language journal with several hundred papers a year is a major national publication, and its standing is a central, verifiable fact of this profile.

Scope: Planning the Grid

Grid planning is the discipline of deciding what network to build: forecasting demand, choosing where generation and transmission should be developed, and designing networks that will remain secure and economical as they grow. Papers in this area of the journal address the methods and studies through which China's grid expansion — the largest sustained programme of network construction in the world — has been planned.

Planning research of this kind has long-range consequences. Decisions recorded and debated in journals like this one shape transmission corridors, substation development and interconnection between regional grids for decades, so the journal's planning literature forms part of the documentary record of how China's modern grid came to have the shape it has.

Scope: Operating the Grid

Grid operation is the journal's second documented anchor. Operating a continental-scale power system involves scheduling generation, controlling flows and voltages, maintaining security against disturbances, restoring supply after faults, and coordinating regional and provincial networks that must function as one machine. Research on those tasks — analytical methods, operating experience, studies of real incidents and of system behaviour under stress — is core material for a journal published from within the grid operator's research system.

The operational emphasis distinguishes Power System Technology from journals of electrical equipment or of generation technology. Its centre of gravity is the network in service: the grid as it is run, hour by hour, by the largest grid operating organisation in the world.

China's grid operation is also a subject of unusual scale in itself. The State Grid Corporation operates transmission and distribution across most of the country, coordinating provincial systems within regional grids that must balance generation and demand continuously, including the long-distance ultra-high-voltage links for which China is known. A journal rooted in that operating system can publish studies grounded in real network data and real operating experience at a scale available in few other countries, and that grounding is a large part of what its readers — operators and planners inside the same system — look for in its pages. The flow of such studies through a Q1 national journal also helps standardise methods across the system, so that a planning or operating technique validated in one province can be examined, criticised and adopted in others through the journal's literature.

Scope: Renewable Integration and Electricity Markets

The journal's documented scope extends to renewable integration and electricity markets, the two subjects that have transformed power-system research in the past two decades. Integrating wind and solar generation at very large scale raises questions of forecasting, flexibility, storage, grid strength and control that Chinese researchers have faced at unmatched scale, and the journal is a natural home for that work in Chinese.

Electricity markets are the other transformation: as China has developed power trading and market mechanisms, research on market design, pricing, dispatch under market rules and the interaction of markets with a physically constrained network has become a recognised part of power-system technology. The presence of both subjects in the journal's stated scope marks it as a journal of the modern grid, not only of its classical engineering.

Scale and Community

Several hundred documents a year — 368 in the SCImago-based table cited above — make Power System Technology a high-volume national journal. Its contributing community spans the State Grid system's research institutes and operating companies, university power-engineering departments across China, and other organisations working on grid technology. Its readers are correspondingly the engineers, planners, operators and researchers of China's grid industry.

That scale matters for a directory profile because it reflects function: this is a working journal of a huge industry, publishing the studies, methods and experience through which that industry develops its technology, rather than a small review title or a house bulletin.

Language and Indexing

The journal publishes in Chinese, appearing in the indexes under both its Chinese title, Dianwang Jishu, and its English title, Power System Technology — the standard dual form for major Chinese journals in Scopus-derived services. Through that indexing its papers are discoverable internationally, and its Q1 category standing is visible to any researcher surveying the Chinese power literature.

For readers outside China, the journal is best approached through those indexes and through the citations of Chinese grid research published in English, where Power System Technology is a standard source for the Chinese state of practice in planning, operation and market development.

Distinguishing the Title

Power System Technology sits among several strong Chinese power journals, and its identity should be kept distinct. It is not Automation of Electric Power Systems, the Nanjing journal of dispatch, protection and grid automation; it is not the Proceedings of the Chinese Society for Electrical Engineering, the society's general flagship; and it is not High Voltage Engineering. Its marks are its grid-wide scope, its Beijing base, its place in the State Grid research system, its publisher Power System Technology Press and ISSN 1000-3673.

Those marks are the ones recorded in this directory, together with its documented scope and Q1 standing, so that the journal's record can be verified against bibliographic databases.

Why the Journal Matters

China's power grid is a piece of engineering infrastructure without parallel in scale, and the knowledge that built and operates it is recorded largely in Chinese journals. Of those, Power System Technology is one of the most prominent: Q1-ranked, high-volume, and devoted to the planning, operation, renewable integration and market questions at the centre of modern grid technology. It is included in this directory as a leading Chinese magazine and academic journal of energy and power engineering.
