The main goal of the program remains a contribution to future EPS development that should be flexible and economically sound. The supporting infrastructure ought to be socially and environmentally acceptable and at the same time fulfilling society needs for EPS reliable operation. This can be achieved only by applying new EPS monitoring, control, analysis and planning system-scale approaches. Research groups’ past scientific results and the applicability of their findings proved the program’s correct orientation. Besides, users of developed solutions show an increasing need for similar products. Activities within the research programme correspond to the following categories (areas of interest): AREA 1: System research in power engineering · Development of methods for fast determination of EPS stability limits. A final goal is to provide the system operator with related information. · WAMS-based EPS disturbance localization. · WAMPAC-based EPS control. WAMPAC concept performs supervision of lower-level controls to assure an EPS secure operation on a system-scale level. · Impact of power transformers’ sympathetic inrush phenomenon on EPS operation . Physical background of the sympathetic inrush phenomenon is not yet fully clear and may endanger EPS operation. · Development of probabilistic forecast method in power engineering includeing probabilistic forecasts. · Development of methods for power system operation considering missing foreign operational data. AREA 2: Smart grids · The development of user models in Smart Grids need to define the technical as well as economic, sociological and legal aspects. · Planning distribution networks, with taking into account the concepts of Smart requires substantial changes to the existing approach to planning. · The development of modern compensation devices for smart grids will focus on control algorithms and testing the operation of the hybrid compensator. · Development of methods for assessment of EPS reliability at increased RES power depending on weather conditions. · Development of distribution system planning methods with smart grid technologies · Development of methods for electric vehicle use as energy storage units. · Smart street lighting for smart cities. AREA 3: Rational use of el. Energy and energy strategies · The concept of contextual model of energy use in in energy-intensive industries. · Development of the model for simulation of small-scale energy storage at EU level (Horizon 2020 project, STORY). · Development of the agent-based model for intelligent control of RES with the active demand response. · Active demand response for providing reserves to the wholesale electricity market.   · A new methodology for determining trading strategies in electricity market based on forecasts of the risk premium. · The methodology for determining market power abuse on the regulated electricity market. · Optimal use of daylight in interiors.
Significance for science
The analysis and planning of the EPS is a complex and interdisciplinary task due to the capital intensity of the field and the limitations posed by the modern society. Given the past performance of the research programme, the references and the set priorities, the programme will focus on the current and relevant issues that are vital for development and operation of our EPS. The said issues are at the same time of high priority also elsewhere in the world. In this chapter we list some of the areas where we expect the most important scientific contributions. · Development and introduction oft the WAMPAC system, · development of control strategies for FACTS devices, · increase of power system transmission capacity, · development of a real time (on-line) power system exposure assessment on the basis of WAMS data, · development of technology and business models for distribution Smart Grids, · development of a new centralized voltage control for Smart Grids, · development of modern compensation control device regulation algorithms in distribution and transmission networks, · development of methods for determining the responsibility for disturbances in the network, and methods for improving the quality of supply, · model for calculation of energy balance of building and impact of different technologies on it, · reliability of power system with distributed and renewable sources of electrical energy, · consideration of common causes and effects of equipment failures within reliability assessment, · development of stochastic methods for electric load, generation, power losses, electricity price forecasts, · development of renewable source (wind) frequency regulation, · development of new methods to estimate investments in electric power systems, · development of new method for modelling of active reserve provision by the demand-side, · development of an adaptive demand agent model and a new specific training algorithm to obtain optimal market strategy, · development of new models and methods of risk management in electricity market.   The above methods require sophisticated tools that will enable static and time domain analyses of EPS. To develop prototypes of EPS components, collaboration with partners from industry is foreseen.
Significance for the country
In the examined field, the two key socio-economic and cultural goals of Slovenian society are confronted: secure electricity supply as a cornerstone of the modern society on one hand, and preservation of the natural habitat and cultural heritage on the other. Seeking of the balance between the two often conflicting goals requires sophisticated technical knowledge and scientific methods. Agreements met at the EU level permeate the society in the form of financial stimuli for the renewable energy production, greenhouse gas emission reduction and energy efficiency. The implementation of all these aspects is directly tied to research applied to the EPS. The biggest influence of our work can be expected in the following fields: · raising the general quality of life, · enhanced security of operation of the Slovenian EPS and consequently better competitiveness of the national economy, because of the reduced number of outages and their shorter durations, · program group members are strongly integrated into the activities of the national Smart Grids Technology Platform, which has as its main objective the development of Smart Grid solutions in the Slovenian industrial companies, thus enabling their participation on the global market, · potential for industrial property (patents), · introduction of new products and services, · better competitive position on foreign markets, · new jobs, · reduce energy consumption and costs in local communities. · Increased use of renewable energy sources in buildings. · improved renewable source usage and participation in widespread implementation of new power engineering technologies into the electric grid, · efficient and improved economic usage of government funds for electric power network planning, · uncertain and variable renewable energy supply and growing demand require increasing operating reserve. Active demand benefits the electricity market operation and help balancing the system. With new technological solutions, demand-side reserve provision is becoming economically feasible, enhancing EPS reliability. · Development of new models and methods of risk management in electricity market. Through introduction of energy markets, new models, the generators and traders face new risks of the uncertain profits. Due to decision making under uncertainty, the deregulated utilities require new knowledge to manage risks, among them portfolio management and risk management. · Members of proposed research group all work in academic sphere (assistants or professors), therefore the proposed research work would directly and positively influence quality of study. · Findings, based on research of this group, will enable development of corresponding regulation that will enable sustainable development and evolution of EPS according to the modern directives of power sector.
