The ongoing upgrade of the electrical power system into a more powerful system known as Smart Grid has both benefits and costs. Smart Grid relies on advanced communication and hence offers better services through improved monitoring, planning, and control. However, enhanced communications make Smart Grid more susceptible to privacy leaks and cyber attacks. Small meters collect detailed consumer data, such as power consumption, which can then become a major source of privacy leakage. Encryption can help protect consumer data, but great care is needed. The popular RC4 (Rivest Cipher 4) encryption has been implemented in the widely deployed smart meter standard—Open Smart Grid Protocol (OSGP)—but has been shown to have major weaknesses. This paper proposes the use of Spritz encryption. Spritz is an RC4-like algorithm designed to repair weak design decisions in RC4 to improve security. A test on performing one encryption took only 0.85 milliseconds, showing that it is fast enough not to affect the operations of a smart meter. Its ability to withstand brute force attacks on small keys is also significantly greater than RC4’s ability.

The encoding of high-resolution energy profile datasets from end-users generated by smart electricity meters while maintaining the fidelity of relevant information seems to be one of the backbones of smart electrical markets. In the end-user sphere of smart grids, specific load curves of households can easily be utilized to aggregate detailed information about customer’s daily activities, which would be attractive for cyber attacks. Based on a dataset measured by a smart meter installed in a German household, this paper integrates two complementary approaches to encrypt load profile datasets. On the one hand, the paper explains an integration of a lossy compression and classification technique, which is usable for individual energy consumption profiles of households. On the other hand, a perturbation approach with the Gaussian distribution is used to enhance the safety of a large amount of privacy profiles. By this complete workflow, involving the compression and perturbation, the developed framework sufficiently cut off the chance of de-noising attacks on private data and implement an additional, easy-to-handle layer of data security.

Electrical energy is one of the most important and vital human needs that cannot be released from daily needs. Customers also have begun to be critical of the purchase costs that must be paid every month. So by increasing electricity rates, improving efficiency in the use of electric power is a major consideration. The Advanced Measurement Infrastructure System (AMI) provides information on the use of granular energy for needs and customers. The IT system at AMI one of which uses EMS (Energy Management System) is an application to collect data from every smart meter installed in the customer, to store it in a database, and to connect the analysis and statistics of the data stored below. In this study aims to provide an analysis of electricity usage patterns by implementing AMI / Smart meters PT. PLN (Persero) by conducting a cluster of 1 phase and 3 phase electricity usage in customers of PT PLN (Persero) UP3 Cengkareng, namely the distribution booths DK60, TG70 and DK242 for 4 months, from November 2018 to February 2019. From the results of the study sought for customers 1 phase DK 60 with a radius of 0.5 produces 1 cluster that is stable every month depending on the customer at this substation is a household class customer, TG 70 requires stable and spending usage in December 2018, and DK 242 fix stable and use customers in the month December 2018 and January 2019, while for 3-phase DK 60 customers tend to be unstable because the customers of this apartment are different, starting from shops, production sites, and CV. TG 70 substations are predominantly places of worship, namely mosques and mosques, so the average use of mosques is higher, and for DK 242 3-phase customers need to be stable and use the highest in January 2019.AMI, System, EMS, Distribution Substation, Phase.

ABSTRAKRiwayat yang disajikan penulis Britania era Viktorian tentang perjalannnya ke Amerikamengasumsikan adanya sebuah jaringan prasarana transportasi. Sistem transportasiterkait dengan riwayat perjalanan (travel narrative) dalam tiga hal, yaitu (1) sebagaibasis material bagi perjalanan, (2) sebagai substruktur riwayat, dan (3) sebagai pokokpembicaraan dalam riwayat itu sendiri. Buku Domestic Manners of the Americans (1832)merupakan model bagi cara infrastruktur transportasi menentukan aspek naratologis,yaitu urutan dan perspektif dalam struktur naratif riwayat perjalanan. Karya tersebut jugamenyajikan transportasi sebagai pokok pembicaraan dalam teksnya itu sendiri walaupun tidaksejauh sebagaimana yang tampak pada The Amateur Emigrant (1895) karya Robert LouisStevenson. Dalam hal ini, The American Scene (1907) karya Henry James juga relevankarena, walaupun tidak secara gamblang membicarakan transportasi sebagai topik dantidak pula menampakkan ciri-ciri riwayat perjalanan, karya tersebut merepresentasicara wawasan Britania-Amerika trans-Atlantik dianggap sebagai sesuatu yang lumrah.Wawasan ini juga memandang menganggap perjalanan trans-Atlantik sebagai semacamperjalanan menembus waktu, yang menunjukkan ketidaknyaman para penulis Britaniaabad kesembilanbelas terhadap transformasi sosial ke masyrakat demokratis yangdirepresentasi secara metaforis oleh pemahaman mereka tentang Amerika.Kata kunci: catatan perjalanan Viktorian, transportasi, wisataABSTRACTNarratives presented by Victorian British writers about their travels to America assume theavailability of a transprtation infrastructure system. Such a system is related to the travelnarrative in three things, namely, (1) as a material base for travel, (2) as a narrative substructurehistory, and (3) as the subject-matter of the narratives. Fanny Trollope’s Domestic Mannerof the Americans (1832) is a model for the way transportation infrastructure determinesnarratological aspects, namely order and perspective in the structure of the travel narrative.The piece also presents transportation as a subject-matter in its text although it does notgo so far as do Robert Louis Stevenson’s The Amateur Emigrant (1895). In discussingtransportation Henry James’ The American Scene is also relevant because, despite it’s notexplicitly speaking of transportation as a topic nor does it show the convential characteristicsof the travel narrative, the work represents a British-American trans-Atlantic world viewas a given. This world view also considers trans-Atlantic travels as a kind of voyage acrosstime, implying the discomfort of nineteenth-century British writers concerning the socialtransition into a democratic society represented by America as a metaphor.Keywords: Victorian travel narrative, transportation, tourism
