In 2016 CEFC China completed the transaction of controlling stock of Kazakhstan national petroleum international corporation, thus reinforcing control over oil terminals in a dozen countries in the Black Sea and Mediterranean region. CEFC China gained four percent of equities in the biggest developed oil gas field in Abu Dhabi. The relevant agreement will be signed soon. Adding CEFC China's sales equity for 10 million tons of oil and gas from Abu Dhabi, CEFC China will be able to increase imports by over 13.2 million tons of crude oil to China each year. The company has succeeded in entering the upstream of West Africa's oil gas industry by completing stock transactions in Chad oil gas project. CEFC China has built in China oil reserve bases with a capacity of over three million cubic meters. The reserve bases have been put into operation and provide strategic oil reserves for China State Reserve Bureau. This project by CEFC China will increase reserves by three days for the whole country. At the end of 2016, the China-Kazakhstan liquefied petroleum gas railway transportation, which was funded by CEFC China, was completed. This project greatly strengthened oil gas import capabilities for China's northwestern region. With the launching and pushing forward of such key projects, CEFC China is completing its international energy strategy. CEFC China will achieve greater goals in oil and gas industry in 2017.

The impacts of Emission trading on building the optimal bidding strategy for a generation company participating in a day-ahead electricity market is investigated. The CO2 emission price in an emissions trading market is evaluated by using an optimization approach similar to the well-developed probabilistic production simulation method. Then upon the assumption that the probability distribution functions of rivals' bidding are known, a stochastic optimization model for building the risk-constrained optimal bidding strategy for the generation company in the framework of the chance-constrained programming is presented. Finally, a numerical example is served for demonstrating the feasibility of the developed model and method, and the optimal bidding results are compared for the two situations with and without the CO2 emissions trading. © (2014) Trans Tech Publications, Switzerland.

The protection misoperation of 1000 kV No. 1 transformer in Jingmen Station was studied in this paper when transformer is charged during the system debug of UHV Pilot Project. The principle of second harmonic current restrained and wave symmetry restrained for regulating transformer differential protection was given according to the inrush current characteristic of regulating transformer. The reasons of the misoperation in SGT756 protection equipment and RCS978C protection equipment were analyzed separately. Three corresponding methods, changing the method of direct resistance test method, adding the erasing magnetism test and improving the protection principle, were put forward by the equipments operation situation in Jingmen station. When these methods were utilized in future China UHV project, the transformer protection reliability can be revised.

The ultra high voltage direct current (UHVDC) project transfers huge capacity energy so that it must have high reliability. Many equipment are developed and produced for the first time without the operation experience. The reliability requirements on the converter transform, valve, reactor etc are stricter than that of the normal HVDC project. This paper studies the operation experience of HVDC transmission project belonging to the State Grid Operation Company since 2000. Some methods are carried out to complete the UHVDC scheme and eliminate the potential problems, like the analysis on the EHVDC operation experience, the earlier control and prevention of major accidents, the similar problems and their regularities. The safe operation level of UHVDC pilot project can be increased in order to fulfill its transmission capacity, reduce the unnecessary blocking and maintenance time.

A power oscillation event is studied after the completion of the Tian-Guang HVDC control and protection system. The magnitude frequency characteristics and phase frequency characteristics of Tian-Guang HVDC control, which added the band-pass filter in the power swing damping (PSD) and power swing stabilization (PSS), are analyzed according to the transient fault record and real progress in Tianshengqiao converter station. The merits and drawbacks of the attenuation and lagging phase in high frequency influenced by the band-pass filter are studied and the reason of continuous power oscillation is as follows: the anti-interference ability of PSD and PSS is weak, and there is no band-pass filter in the control transfer function. Three corresponding methods including modifying the open strategy of PSD and PSS, adding the band-pass filter in the control transfer function and modifying the parameter of PSD and PSS, are put forward to avoid the high frequency power oscillation.

The cascading failure in China South Power Grid caused by an explosion accident of 500 kV circuit breaker is analyzed, and it is pointed out that the explosion accident of 500 kV circuit breaker occurred in Yandu substation simultaneously led to the commutation failures of three EHV/UHV DC transmission lines, i.e., the ±500 kV DC transmission line from Gaopo to Zhaoqing, the ±500 kV HVDC transmission line from Tianshengqiao to Guangzhou and the ±800 kV DC transmission line from Chuxiong to Suidong, and further the accident led to the forced outage of valve cooling system for Pole II of Guangzhou converter station. Because Zhaoqing converter station is electrically close to 500 kV Yandu substation, thus Zhaoqing converter station is subjected to the most severe affection, and the DC voltage of ±500 kV DC transmission line from Gaopo to Zhaoqing drastically fluctuated and a lot of harmonic components appeared and directly made the bipolar DC line under-voltage protection (27 du/dt) acted. After the success bipolar re-starting of ±500 kV DC transmission line from Gaopo to Zhaoqing, the still existed forced outage of valve cooling system for pole II led to the pole II re-blocked. The author analyzes the spread of the accident as well as the related hidden danger, and proposes effective rectification measures to prevent the reoccurrence of similar cascading failures.

The ±800 kV ultra high voltage direct current (UHVDC) transmission system is an extraordinary challenge to system design and equipment manufacture. China Southern Power Grid Company (CSG) organized research and design for the construction of Yunnan-Guangdong ±800 kV UHVDC project (YG UHVDC project), and got large technical breakthroughs and advanced technologies for ±800 kV UHVDC transmission systems. These advanced technologies include power system stability, main electrical wiring, overvoltage and insulation coordination, external insulation, electromagnetic environment, control and protection, and arrangement of the main equipments. Meanwhile, CSG led the researches on specification of main equipments, such as converter valve, converter transformer, dry-type smooth reactor and others involved in the whole process management of equipment supervisions. The YG UHVDC project was put into commercial operation in 2010 as the first pilot ±800 kV UHVDC project in the world. The whole system operated in a stable and smooth manner, and the UHVDC equipment and control systems passed the test under the practical operation in CSG bulk power system, which shows that the design and research objectives were achieved.
