Information System for Monitoring and Forecast of Building Heat Consumption

In this paper an implementation of a web-based monitoring system, which introduces the components and principles of this monitoring system, and provides the model of heat consumption prediction is presented. The general architecture of the information system is described.

The model for decision support on design of the hybrid renewable energy system

The purpose of this study is a solving the multicriteria task of choosing the optimal structure of a hybrid energy system with renewable sources. To achieve this goal the models for making decision on determination of all possible configurations of energy system and a selection of the optimal structure of its elements for each of the configuration were proposed. The proposed model differs from the existing ones by the ability to generate all possible configurations of the energy system depending on existing on the market installations of renewable energy sources.

Models of Decision Making in Planning the Structure of Hybrid Renewable Energy System

This paper is devoted to the development of scientific and methodological foundations of improvement the information support of decision during planning stage of creation hybrid energy system with renewable energy sources. Here are proposed models of multiple-criteria decision-making for choosing the optimal structure of the grid within three interrelated valuation scenarios by defining a plurality of quality criteria in the form of explicit dependencies from linguistic variables. It was improved the model of structure synthesis of hybrid energy grid by using the methods of combinatorial logic. The model of analysis the technical and economic parameters of the system are proposed accordance to operating logic of the real system. Based on developed models in paper is proposed the information technology of decision support planning hybrid renewable energy system structure.

Complex information and technical solutions for energy management of municipal energetics

The tools for energy management of district heating on the consumer side are proposed in this article. The information system of making decision support in the management of heat supply which carries out the heating monitoring, forecast of heat consumption and decision support of the heating modes regulation is developed. To make the decisions on heating modes regulation the system of automatic heating control in individual heating substation is proposed. Using of these systems allows managing the heating system in individual heating substation and reducing heat consumption on the consumer side.

The Forecasting of the Daily Heat Demand of the Public Sector Buildings with District Heating

This study is devoted to the increasing of the heat energy demand forecasting accuracy for district heating of the public sector buildings.

Complex mathematical model for computer calculation of delivery and heat distribution in pipeline system

Authors propose a mathematical model for determination of temperature of stream, parameters of water on an exit from a pipe and losses of pressure on a friction depending on a temperature on an entrance in a pipe.
