Abstract
The main aim of the research programme remains the development of the methods for analysis and development of the electric power system (EPS) as to maintain security of electricity supply. The programme success in the past period exceeds expectations and affirms the research direction. The research topics are relevant, applicable in the industry and most of all sought after by the end users. In the research programme, the main focus will be on the following fields: AREA 1: System research in power engineering · Development of the methods for quick determination of the EPS stability limits. The goal is an application for on-line stability limit determination. · On-line state estimation and threat level based on WAMS system. The method will estimate the threat level in real time. · Determination of FACTS equipment parameters using the stability edge maximization. It will encompass the issue of dynamic control of FACTS equipment for EPS stability enhancement. · Forecast method development in electric power systems Development of a combined adaptive method for uncertain renewable generation, load and electric power system losses. · Participation of renewable sources in frequency regulation. New algorithms of renewable sources frequency control and regulation scheme adaptions. AREA 2: Smart Grids · Development of technology and business models of Smart Grids. In addition to technical solutions, the economic, regulatory, and sociological aspects of Smart Grids deployment models have to be researched. · Advanced concepts of voltage control in Smart Grids. Development and testing of advanced – centralized voltage control in distribution networks are required. · Development of modern compensation devices for Smart Grids. Development of additional control algorithms for compensation devices in distribution and transmission networks is required. · Development of methods for assessment of reliability. Development of methods for assessment of reliability of power systems, which include an increased number of distributed sources of electrical energy. Special attention will be placed to consideration of causes and effects of failures, which can simultaneously affect a larger number of distributed sources. AREA 3: Rational use of el. energy and Energy Strategies · Assessment method for efficient investment in electric power grid. Development of new assessment methods for efficient investments into distribution grids. · Rational use of el. energy in local community. The typical energy consumption in local community will be determined. The model for calculation of energy use and possible saving due to use of renewable energy sources will be made for different segments (public buildings, street lighting, households …). · The influence of active demand on electricity market. Development of adaptive demand agent model, including a new learning algorithm and a criterion for optimal market strategy. Development of new models and methods of risk management in electricity market.
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 some of the areas, in which the most important scientific contributions have been achieved, are listed. • 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.
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 does directly and positively influence quality of study. • Findings, based on research of this group, enable development of corresponding regulation that will enable sustainable development and evolution of EPS according to the modern directives of power sector.
