Critical loads and service continuity
Power systems, critical for the mission of their loads (hospitals, data centers) and/or equalized to mission critical for the vulnerability of their supplying network, need a “partition system”, local fortified structure, interface between network and utilization, designed as a service continuity “castle” and managed to guarantee an adequate response to every emergency. This operational management must ensure the efficacy of the partition system in maintaining dependability and functional safety against the loss service continuity during fault events, maintenance demands and emergencies for external stresses. The system structure design can apply a “Darwinian” approach aimed to mitigate also the external stresses and service losses against expected dangerous events such as earthquake, fire and other events that can cause long blackouts from the main network. Preventive measures to reduce the earthquake consequences, predictable in that location, are based on the principles of controlling and mitigating the seismic stresses. A special power distribution, herein defined as “brush distribution” are proposed for critical buildings exposed to seismic risks and for road tunnels with higher risk in case of fire event. The design of a power system requires a comprehensive and permanent design and highest consideration of competence of system maintenance operators.

Qualification and condition monitoring of safety related instrumentation and control cables of nuclear power plants
The safe operation of nuclear facilities is based on that the information and control (I&C) cables have to be capable to fulfil their safety function even during design-based event (DBE). It is the role of qualification to ensure that the cable can be demonstrated to perform as specified performance requirements during normal and DBE environment. The nuclear cable qualification is mainly based on accelerated laboratory tests, which is usually performed by cable manufactures according to the standards. However, these examinations have been used for decades, the relationship between the accelerated ageing and the ageing at operation conditions is still in the focus of scientific interest. The background of accelerated ageing tests is that by increasing of the intensity of stressors (temperature, voltage, dose-rate etc.), the time of the ageing test can be reduced. Recent studies have revealed several phenomena (diffusion limited oxidation, inverse temperature effect etc.), which lessen the reliability of these examinations. Hence, the condition monitoring of the safety related cables is the important aspect of the long term operation of nuclear power plants.
The Chair is committed to create an easy-to-follow schedule that is professionally remarkable, exciting, and would also leave you some time for making long-term connections.

We are pleased to announce the Technical Tour which will drive us to the Krško Nuclear Power Plant (NEK) which is located in Vrbina in the Municipality of Krško, Slovenia. The plant was connected to the power grid on October 2, 1981 and went into commercial operation on January 15, 1983. It was built as a joint venture by Slovenia and Croatia which were at the time both part of Yugoslavia. NEK is equipped with a Westinghouse Pressurized Light Water Reactor of 2000 MW thermal power. The power plant's net electrical power is 696 MW. It is connected to the 400 kV grid supplying power to consumer centers in Slovenia and Croatia. NEK generates over five billion (10^9) kWh of electrical energy per year, which represents approximately 40% of the total electricity produced in Slovenia and 15% of Croatia's power production. The tour of NEK will include movie presentation of the plant, presentation and discussion with the representative of NEK and a guided tour of the classical – nonnuclear part of the plant. The tour will take around 3 hours.
Later on we will continue our tour to the Hydro plant Vrhovo which is 40 mins away from Krško. Hydro plant Vrhovo is situated on the river Sava. The hydro plant operates in a daily flow regime with accumulation, which has the role of a front basin for the Sava chain of hydro plants. The concrete gravity dam is 27 m high. The plant’s electrical power is around 34 MW. On average, it generates around 116 GWh on a yearly basis. The tour will take around 1.5 hours.
In the energy sector, the life-time of the equipments and power plants we design is about 40-60 years. Nowadays the generation YZ is used to change their job in every few years. During the workshop we are looking the answer to the question "What kind of challenges young professionals may face in the energy industry?"
The US-based Association of Energy Engineers (AEE) is your source of info & networking in the dynamic fields of energy engineering, energy management, renewables, power generation, energy services, sustainability, and related areas . The Seminar focuses on energy management and systems, energy saving solutions presented by our honorable guests:

Mistakes to Avoid in Analyzing Your Energy Audit
Sustainable energy projects should earn a profit, but how do you determine if your project will make money or lose money? This presentation shows the correct analytic approach, considering the cost of capital, and explains six mistakes to avoid.

Energy Auditing on Buildings
Energy audit is a term used worldwide. In many countries the government promotes conducting energy audits, and in some countries energy audits may be required to be carried out at regular intervals. In both cases, the audits may be specified by forms and regulations. These regulations tend to differ in each country, the goal remaining the same as to give advice to the owners and operators about a more efficient use of resources (electricity, heat, fuel and in some cases water).

Energy Efficiency for a Clean Energy Future
The energy efficiency industry is experiencing a major transformation globally, with more changes in the past 5 years that in the previous 100 years. With the continued decline in the price of renewal and alternative energy, advancement of systems and technologies and the addition of distributed generation and microgrids, the traditional energy model is changing for both end users, cities and utilities. Many cities and countries are now mandating 100% power from renewable energy and requiring all automobiles to be all electric vehicles. How does this affect utilities, energy engineers and the highly skilled workforce required to implement and operate in this rapidly evolving energy field? We will look back at the last 40 years and how you, AEE professionals and future energy engineers, will improve the quality of life and drive economic advancement in your communities and the world through implementing advanced energy solutions.
Panel discussion on effects and challenges emerging in renewables' integration process into 21st century energy systems
The different types of energy systems are mainly constructed and designed in a way that corresponds the last century's solutions. Today's tendencies, meanwhile, are pointing to new directions, all of which has to be carried out within the barriers of the present systems.
Technical and economical challenges arise from the need to maintain the balance between load and generation at all timescales, besides the concerns about energy security and development, stringent climate policy, and the increasing challenges due to the changing nature of the twenty-first century energy system.
What are the effects, challenges, and how can we take advantage of them?

We are pleased to announce the Joint IEEE Workshop. The first section, starting at 8:30 is hosted by the IEEE Slovenia Section and the University of Ljubljana where the representatives of these institutions greet the audience.
After a short coffee break, Prof. Georges Zizzis, IAS president, Ms. Lesley Arakkal and Dr. Peter Magyar, IAS Director of Chapter Development introduces the activities of the society and the chapters. Subsequent to the introduction, a small presentation is going to be held about the activity of the BUTE SB PES/IAS Chapter and the Hungarian Student Chapter of the Association of Energy Engineers (AEE).
The essence of the workshop is the inauguration ceremony of the Slovenia Section IAS Chapter and the University of Ljubljana SB IAS Chapter. As the closing event, Prof Georges Zissis delivers a lecture on Light beyond Lighting, frontiers in Lighting Technologies: The human-centric intelligent lighting challenge.
The participation is free of charge, however prior registration is required. Registration is available under this link.
