In the background of energy transformation, the world has witnessed the rapid development of new energy generation, with the proportion of capacity and electricity continuously increasing. However, different countries and regions have great differences in the access level of new energy. When a high proportion of new energy is connected to the system, it is neither scientific nor reasonable to reflect the development and absorption level of new energy only by such indicators as the proportion of new energy installed and the proportion of electricity generated. This paper analyzes the development status of new energy at home and abroad, and constructs the evaluation index system of the access level of new energy in power grid. Based on the evaluation index system, the access levels of new energy in different countries and regions are compared and analysed. At last, several key issues that need to be solved to achieve the goal of high proportion of new energy access in China are put forward.

The difference between registered active power and spent unregistered power represents the losses at power grid. This paper treats problems related to losses caused by nonlinear loads connected to the power grid. In recent years the load profile of power consumers turned from energy-waster linear to energysaver but non-linear loads. The main cause of the losses appears due to the lack of adequate measurement equipment. Namely, common household power meters register only active energy, while power meters for industrial application register reactive energy as well. This approach does not follow the change of the enduser profile. Tendency of improving energy efficiency brought wide use of switching mode regulators and replace old incandescent light bulb with new energy saving lamps (CFL - compact fluorescent lamp, LED bulb). Therefore, the number of non-linear load drastically increased. Registering only active component of power at consumer?s side does not depict the real profile of the consumption. Therefore, in this paper we analyse and quantify the effects of nonlinear loads at power losses. As a result we suggest an efficient method for measuring the distortion component of power. The method relays on low-cost upgrade of commercial electronic power meters. The presented results of measurements on small non-linear loads confirm the proposed technique. Besides, they prove the importance of measuring all components of apparent power and justified their use in billing policy. The implemented set-up is based on power meter manufactured by EWG of Nis.

Monitoring of warehouse inventory data processing is an important thing for companies. PT Talaga mulya indah is still manual using paper media, causing problems that have an effect on existing information, namely: problems with data processing of incoming and outgoing goods. And the difference between data on the amount of stock of goods available with physical data, often occurs inputting data more than once for the same item, searching for available data, and making reports so that it impedes companies in monitoring inventory of existing stock of goods. Which aims to create a system that can provide updated information to facilitate the warehouse admin in making inventory reports, and reduce errors in input by means of integrated control. In this study, the authors used the data collection method used in this analysis using the method of observation, interviews, and literature review (literature study). For analysis using the PIECES analysis method. Furthermore, the system design used is UML (Unified Modeling Language). The results of this study are expected to produce the right data in the process of monitoring inventory data processing, also can provide the right information and make it easier to control the overall availability of goods.

The introduction of Eurocode in Kazakhstan allows for the application of modern technological innovations and the elimination of technical barriers for the realization of international projects. It is significant to study the international standards and design requirements provided in Eurocode. This study presents a comparative analysis of Kazakhstani and European approaches for the geotechnical design of foundations and provides the design methods in the considered codes of practice. Three different types of foundations (i.e., raft, pile, and piled raft foundations) were designed following SP RK 5.01-102-2013—Foundations of buildings and structures, SP RK 5.01-103-2013—Pile foundations, and Eurocode 7: Geotechnical design for the Nur-Sultan soil profile. For all three types of foundations, the calculated results of bearing resistance and elastic settlement showed the conservativeness of Eurocode over SNiP-based Kazakhstani building regulations, as the values of bearing resistance and elastic settlement adhering to Kazakhstani code exceeded the Eurocode values. The difference between the obtained results can be explained by the application of higher values of partial safety factors by Eurocode 7. Sensitivity analysis of the bearing resistance on foundation parameters (i.e., raft foundation width and pile length) for the Kazakhstani and European approaches was performed to support the conclusions of the study.

The Impact

Purpose Library impact and how to evaluate it has been debated for a number of years. While the activity – the busy-ness – of the library is now routinely measured and described, the difference the library makes is less tangible and harder to measure. Libraries in all sectors and worldwide are grappling with this issue, and the purpose of this paper is to summarise international standards available to support them. Design/methodology/approach The first international standard concerning library impact, ISO 16439 Information and documentation – methods and procedures for assessing the impact of libraries, was published in 2014 after several years in development. Findings The standard describes a range of methods for assessing library impact which have been used across the world in a variety of libraries in all sectors. Originality/value This paper summarises the key methods described in the standard, and gives references for further reading.

The World Economic Forum has identified that the oil and gas (O&G) industry must lead the process of its own transformation by innovation and multistakeholder collaboration. The Capital Project Complexity initiative is an industry-wide, noncompetitive collaboration on standardisation and use of procurement specifications. Australia is now a major contributor to this collaboration which has brought together all the major O&G operators through the International Association of Oil & Gas Producers (IOGP) network and the standardisation bodies including International Organization for Standardization (ISO), American Petroleum Institute Standards, European Committee for Standardization, Gulf Cooperation Council Standardization Organization, Standardization Administration of China, Standards Australia (SA) and many more. The focus is on developing common international standards through an IOGP Standards-ISO/TC67 link and standardised equipment specifications linking to these standards through IOGP-JIP33. Australia contributes via SA’s mirror committee ME-92, which is now fully established with direct involvement in the ISO/TC67 9 subcommittee areas and 13 working groups covering 261 current and developing standards. In September 2020, the first of these standards, AS ISO 29001, was identically adopted as an Australian standard. With the Australian experts now ensuring ISO Standards will incorporate Australian industry expertise, knowledge and regulatory requirements where possible future revisions will enable them to be adopted as the next revision of the Australian standard. This industry-wide collaboration will ensure future project costs are optimised and safety enhanced through use of the global industry knowledge while also reducing the need to write local standards. This study describes Australia’s strategy being pursued to align with the global industry. It also provides information on how this network is supporting the development of knowledge transfer to the decommissioning and new energy industries that will form Australia’s future.
