The paper refers to the analysis of load curves for individual electricity consumers settled according to the G-tariff as well as to the standard profiles being developed for such a consumers group. Results of analysis of influence of the sunset hour and air temperature on the shape and parameters of electrical load for selected consumer groups have been presented. The models of the influence mentioned above on the consumers with load strongly related to those parameters have been developed. The results obtained have been compared to those from another analysis for standard profiles developed by Polish Association for Electrical Energy Transfer and Distribution; the remarks on construction of standard models and their application to the load estimation for defined consumer groups have been expressed.

In case you didn’t catch word, I’ve been nearly invisible here on CleanTechnica for the past few weeks because our 2nd daughter (Julia) was just born on September 9 and I’ve been playing mommy + daddy to our 2-year-old daughter Lily for a few weeks, while also trying to help mommy + the newborn as much as I can. But we have a conference fast approaching, so I’m again raising my head above the editing + content curation side of CleanTechnica. Wrocław (where I live) is the home of our next Cleantech Revolution Tour conference (register for free here). It is also one of two current “European Capitals of Culture” — which is not to say it’s Europe’s #1 cultural capital, but it has a lot to offer and is a great city to visit. (You can read more about the European Capital of Culture program here.) The biggest draw for conference attendees, though, is certainly the conference itself. Since I last wrote about it, we have signed up several more exciting and expert presenters. Additionally, Nissan has joined as a sponsor of the conference, and Radio RAM, GRAMwZIELONE, and Idea Place have jumped on as supporters. These four partners join initial sponsors and partners Europejski Instytut Miedzi (aka European Copper Institute), GridHub, Important Media, TechBerlin, Leonardo Energy, and CleanTechnica (of course). Nissan will be bringing not only LEAF electric cars for test drives, but also e-NV200 electric vans. I’ve never driven the latter, so I’m personally excited about that opportunity! Aside from all of the topics and speakers I announced in my previous article about the conference, we have several new ones to highlight. You can check out the conference website for more details, but here’s a summary of topics we’ve added: Remember, to make the conference as accessible as possible, we have made registration free! Join us in Wrocław for some cleantech inspiration and fun! Here are short bios of some of the newly committed speakers: Arsenii started the green transport revolution in Ukraine. As a technical engineer and experienced businessman, he has always been engaged in the car market and has worked in the EV industry since 2008. He initiated widespread awareness of electric transport in Ukraine (bioauto.com.ua) and endeavoured to change legislation and attitude towards green transport and charging networks. Since 2015, Arsenii is a Chairman of the Board of Electric Vehicle Association of Ukraine (ev-ua.org), and in the same year, became a certified engineer-technologist for the assembly of EVs.

That’s a pretty stellar lineup of new speakers, no? I’m super excited about the fascinating presentations we’ve lined up, and I’m not saying that to toot my own horn — Jacek Fior has actually been the one leading the event organization and planning, so the credit really goes to him. The people I’ve brought in have largely come through previous connections and good luck.

International Conference on the European Energy Market, EEM | Year: 2015

In this paper the effectiveness of demand-side management using zonal tariffs for households is analysed on the case of tariff offer proposed to customers in north-western Poland with the aim to widen the use of electricity for heating purposes. The price elasticity of customers settled according to two zonal tariff was determined using standard load profile of customers published by regional distribution network operator. The costs associated with the applied mean of demand side control were identified and the tariff effects assessment were made taking into account the benefits reached by energy supplier and network operators forming together the considered tariff offer. The analysis presented enabled to formulate some recommendations concerning TOU residential tariff restructuring to improve its feasibility and to create possible prospective income in result of peak load reduction. © 2015 IEEE.


The article presents the possibility of using artificial neural network for interpretation of dissolved gas in oil analysis results (DGA method), which is one of the common used methods for diagnostics of power transformer state evaluation. In the work, the network topology, regarding to different methods of oil-paper insulation defect classification (e.g. IEC, Duval's, Dornenburg's, Roger's method), was designed and different type of network were tested. After the selection of the most optimal neural network, a functional computer application was created.

International Conference on the European Energy Market, EEM | Year: 2016

During the summer of 2015 the transmission system operator in Poland was forced to introduce limitations on electricity consumption to important industrial and commercial customers. In absence of sufficient generation reserve in power system this paper undertakes an analysis of the implementation of demand response program based on critical peak pricing for residential customers in a research of the resource that can prevent such shortages and resulting energy price increases. Making use of standard load profiles for customer group under analysis the critical price levels and the price discounts for program participants were designed allowing for the prospective efficient recruitment of program participants. In this way the demand response resource able to offer the important load reduction level comparing to the normal hourly load of participating customer group could be created in a manner financially neutral for the tariff system in force. © 2016 IEEE.


The aim of this paper was to study the behavior of a transformer station during summer and winter loads. It has been shown that, in these two periods we get losses from the power load.


A method of electrical Power systems Court circuits calculation is proposed in this paper. To analyze the chosen power transformer sstation we have adopted the admittance matrice method at the nods of the network.
