Emergence of the Energy Internet (EI) demands restructuring of traditional electricity grids to integrate heterogeneous energy sources, distribution network management with grid intelligence and big data management. This paradigm shift is considered to be a breakthrough in the energy industry towards facilitating autonomous and decentralized grid operations while maximizing the utilization of Distributed Generation (DG). Blockchain has been identified as a disruptive technology enabler for the realization of EI to facilitate reliable, self-operated energy delivery. In this paper, we highlight six key directions towards utilizing blockchain capabilities to realize the envisaged EI. We elaborate the challenges in each direction and highlight the role of blockchain in addressing them. Furthermore, we summarize the future research directive in achieving fully autonomous and decentralized electricity distribution networks, which will be known as Energy Internet.

Distribution System Reliability

Reliability of distribution networks is a factor that greatly affects customers as consumers of electricity. Analyzing and calculating the reliability of distribution networks are determined by the reliability index including SAIFI, SAIDI, CAIDI, and ASAI. On the other hand, smartphone technology is growing rapidly with a variety of applications to help simplify and accelerate human work in several fields of work. This paper delivers the design of an Android-phone-based analytic tool for distribution system reliability index measurement by developing it on Android application software. This application is named KALINDA, stands for Kalkulator Indeks Keandalan (Reliability Index Calculator), and created by using Android Studio IDE. We compare the data result between KALINDA calculations and manual calculations. The results obtained from the KALINDA application are declared to be valid accurate.

Penyaluran energi listrik pada jaringan PT PLN PERSERO khususnya pada jaringan distribusi sering mengalami kegagalan yang disebabkan arus bocor pada isolator keramik. Intensitas kerusakan disebabkab oleh polutan debu yang menempel pada permukaan isolator, ditambah pula dengan kelembaban udara yang ada di daerah tropis seperti Indonesia. Hal ini secara kumulatif, menyebabkan flashover pada permukaan isolator dan menyebabkan kegagalan penyaluran energy listrik pada jaringan. Pengaplikasian Silicon Rubber sebagai bahan pelapis isolator dapat mengurangi polutan debu yang menempel pada permukaan, hasil penelitian menunjukkan bahwa parameter tegangan akan berpengaruh juga pada besarnya arus bocor yang mengalir pada permukaan isolator. Semakin tinggi tegangan kerja akan memperbesar nilai RMS arus bocor yang mengalir. Terukur pada level tegangan 20 kV arus bocor yang terukur memiliki RMS sebesar 0,0432 A dengan THD sebesar 15,76 % dengan beda fasa arus bocor terhadap tegangan sumber bersifat leading hampir mendekati α = 900. Distribution of electricity in PT PLN PERSERO network, especially in distribution networks often fails due to leakage current in ceramic insulation. The intensity of damage caused by dust pollutants that are attached to the insulation surface, coupled with the humidity of the air in tropical areas such as Indonesia. This cumulatively causes flashover on the insulation surface and causes failure of electricity distribution to the network. The use of Silicon Rubber as an insulating coating can reduce the amount of dust contaminated on the surface, the results show that the voltage parameter will also affect the amount of leakage current flowing to the insulation surface. Higher working voltage will increase the current RMS leakage value. Measured at a voltage level of 20 kV the current leakage was RMS 0.0432 A with THD of 15.76%, phase difference of leakage current to leading source voltage is almost close to α = 900.

The paper investigates the mid-term results of the tariff regulation influence on the amount of capital expenditures in Russian electricity distribution sector. We estimate panel data with the dynamic investment model using system GMM method. We showed that horizon of tariff regulation period is statistically significant and transition from the short-term regulation to the long-term tariff system had positive effect on the amount of regulated companies’ investments. At the same time we found that the design of long-term regulation applied in Russia in 2009–2013 (type of RAB-regulation and long-term indexation) was not statistically significant to the amount of investments. All over all, the amount of investments in electricity distribution networks has similar to European peers explanatory factors. The obtained results are important to the further improvement of regulation in power energy and can be applied in district heating as well.
