Özet
The increase in the need for electrical energy day by day causes the number of connections in the network to increase and planning becomes more difficult. The power flow analysis is an integral part of the work carried out on the power systems and it is can easily be performed thanks to the increased speed and capacity of computers. However, in a system with thousands of buses, presenting the results to make predictions and quickly determine the status of the system is also a major problem. The use of geographic information systems is recommended to provide situational awareness for power system reliability, especially due to blackouts that have occurred in many countries in recent years. Rather than proposing a new power flow algorithm, this study introduces an integrated GIS-based (ArcGIS) visualization framework that enables the geographical interpretation of power flow analysis results obtained with the Power System Analysis Toolbox (PSAT) software. In addition, a long-term planning study was carried out by using the real interconnected 66-bus system in Istanbul province of Turkey. This region was chosen because it consumes more electrical energy than many OECD countries due to its high population density and industrial load intensity. It also has three Bosphorus crossings due to its geographical features. It has been observed that the results obtained by using free software are very close to the results of commercial package program (PowerWorld Simulator) that can perform both analysis and visualization. The proposed workflow and framework supports multiple visualization layers and long-term planning scenarios, providing an effective decision-support environment for transmission planning and system operation.
