President Bush’s National Energy Policy, Clear Skies and the Global Climate Change Initiatives form a comprehensive roadmap to a secure, clean, reliable, and affordable energy supply for the future. These far reaching policy proposals rely heavily on the development of distributed energy systems. The cornerstone of distributed energy systems is the emergence of Integrated Energy Systems (IES), which will permit consulting engineers to substantially improve energy efficiency. Thermally Activated Technologies, in general, and absorption chillers, in particular, are increasingly being viewed as an important element to effectively apply IES designs to the American building stock. This paper will examine testing, demonstration projects and commercial applications of combining absorption chiller equipment with microturbines, engines, combustion turbines and thermal solar systems. Technical challenges of coupling absorption chillers to prime mover exhaust streams will be explored. Application specific integration of coincident power generation and thermal energy supply to satisfy building loads will yield economic metrics that will determine which combinations of prime mover and absorption chiller will succeed in the market place today and which combinations require more research and development.

The conversion of existing energy systems to intelligent integrated energy systems can happen only if economic benefits due to introduction of the intelligent integrated energy systems will exceed required level of investments. Thus, it is necessary for every optimal design energy systems problem according to the purposes of the study to determine various aspects of equipment configuration, investment and a proposed unit commitment on a case-by-case basis. The studies, taking under consideration energy efficiency of renewable energy units, are particularly important as environmental safety standards are increasing. In the paper optimal design of prosumer energy supply system problem in the intelligent integrated energy system was investigated. For this purpose a super structure for an energy supply system includes different generating capacities with relevant power range. The superstructure for prosumer energy supply system consists of an electric boiler, a gas-fired boiler, a solar photo-voltaic, a solar heating system and a gas-fired CHP. An ability of district energy system to receive the excess generating energy is restricted by the constraints. The heat and electricity tariffs and the received to district energy supply system energy constraints are varying according to time period. As a result of this study, cost-effectiveness analysis of chosen equipment configuration was undertaken.

The article considers the information and technical aspects of an innovative autonomous integrated power plant management, including alternative energy sources and a diesel generator set, as well as controlled inverters that provide energy supply to consumers of various priority categories, which can be used in the Arctic regions of the Russian Federation. The main aspects of creating innovative systems are considered and it is determined that the creation of integrated energy systems requires a significant deepening of cooperation between national producers in order to ensure the scalability of integrated energy systems by ensuring the unity of information means of data exchange between individual modules and the control system. It is shown that a specific requirement for control systems of complex power plants is the requirement of high autonomy, including the ability to provide consumers with electricity under variable environmental conditions without direct intervention of operational personnel. The article substantiates the division of the information and algorithmic support of the control system of a complex power plant into two modules – analytical and control. For the analytical module, an algorithm is proposed that ensures the development of control solutions in a complex energy system, ensuring the stability of energy supply to the most important consumers. At the same time, the algorithm provides an increase in the reliability of the energy storage device based on Li-Ion batteries used in the system not only by eliminating excessive charge and deep discharge, but also by reducing the number of charge/discharge cycles. The solution of system autonomy problem is provided by a multivariate algorithm for predicting weather conditions using statistical data and methods for analyzing fuzzy time series. The intelligent control algorithm was implemented in C++, the weather forecasting algorithms were implemented in Python using the ANFIS library.

Integrated Energy Systems

Currently, operation control and expansion planning of energy systems occurs separately for local systems and tasks. Traditionally, the considered energy systems unite large energy sources, such as hydro, thermal power plants, combined heat and power plants, boiler plants and electric and pipeline networks distributed over a large area. New trends in the energy sector necessitate a revision of the principles of the construction of energy systems and creating integrated energy systems. THE PURPOSE. Combining existing energy systems into a single integrated system with many interconnected and coordinating elements can contribute to the implementation of new functionalities, the use of more advanced technologies in operation and the active participation of consumers with distributed generation in the energy supply process. METHODS. To study integrated energy supply systems, it is proposed to use a multiagent approach, which is one of the promising areas for the study of complex systems. This approach is used in many subject areas to study systems involving a large number of elements with complex behavior. Such systems include integrated energy systems, the modeling and analysis of which on the basis of a multiagent approach is formed by a multitude of interconnected agents that exchange various data with each other. RESULTS. Based on the research results, the active structure of a multiagent system is proposed for the calculation and optimization of integrated energy systems and, taking into account their main features and properties, in the framework of which the agents of the multiagent system, their goals and objectives are determined. CONCLUSIONS. Based on this structure, a model has been developed that allows modeling integrated energy systems. The experiments carried out using the developed model showed its efficiency, practical applicability and prospects for further development.

The article considers the possibility of introducing digital and intelligent systems in the electric power industry, including the analysis of the consequences after the introduction of new technologies on the economic, social and technological side. Currently, the concept of distributed generation is being used more and more often in the global energy arena. This is certainly a trend in the energy sector. The current level of technological development in the energy sector is quite high, but in order to continue to increase competitiveness, we need a further transition to digital and intelligent energy systems that will increase the reliability, quality, environmental friendliness and automation of energy supply.
