Abstract
The aim of our research is to develop a new software tool – the Computing and Geo-information System for study of prospective interstate power grids expansion. The new software tool developed by the authors consists of several functional parts (software modules): graphic module for visual analysis of processed data, geo-information and cartographic module, module for working with the integrated ORIRES model (model for optimization of power systems expansion and their operating modes). In this paper, we consider features and technical description of the new software tool. The obtained results of the integrated ORIRES model in tabular, graphic and cartographic forms are presented.
Highlights
The formation of interstate power grids (ISPG) in various regions of the world is due to positive effects to be obtained: increased reliability of electric power systems and uninterrupted power supply, wide involvement of renewable energy sources, and significant economic benefits
Each module is intended to solve specific problems. They can be divided into three groups: 1. Optimization and computing problems: a. assessment of the effectiveness of interstate electric ties; b. assessment of the integration level and efficiency of interstate power grids; c. optimization of electricity generation capacities and operating modes for energy power systems (EPS); d. study of EPS and ISPG expansion in different regions
The cartographic module uses three different types of data: 1) raster data used as a background layers for analysis of the map of selected territory, 2) vector data – borders of all administrative regions; the CGIS can be used to study of ISPGs in any regions, for the Northeast Asia (NEA), 3) graphical layers for visual analysis, containing certain energy information from the database about the modelled objects, as well as obtained during calculations on the model
Summary
The formation of interstate power grids (ISPG) in various regions of the world is due to positive effects to be obtained: increased reliability of electric power systems and uninterrupted power supply, wide involvement of renewable energy sources, and significant economic benefits. ISPG requires justification of its technical and economic efficiency, forecast of further expansion, coordination of economic and political interests, compliance with the technical standards of the participating countries, and consideration of many other aspects [1,2,3]. These researches require a lot of preliminary work to collect and analyze a huge amount of energy and power data, technical and economic calculations, and significant intellectual and information resources. The authors have developed the Computing and Geoinformation System (the CGIS), which consists of a graphical (geoinformation) part and a computing part with an integrated ORIRES model and with the ability of its multiple configurations [7,8,9]
