Pakistani Transmission Grid Model (PTGM) ######################################## Version: 1.0 Date: 01.09.2015 Description of the data files ============================= All data is contained in the Excel file "ptgm.xlsx" which contains 5 sheets. Each sheet is also provided in form of a CSV file (comma-separated values). List of sheets / CSV files: - Nodes / ptgm_nodes.csv - Links / ptgm_links.csv - Cities / ptgm_cities.csv - Industries / ptgm_industries.csv - States / ptgm_states.csv The list of nodes (vertices) and the list of links (edges) form a multigraph, representing the substations as well as the transmission lines of the Pakistani transmission grid. Some major power plants that are directly connected to the transmission grid are also included. Both nodes and links have certain attributes, such as the geographical position of the nodes (latitude and longitude), and physical parameters of the transmission lines etc. The so defined grid is visualized in the file "ptgm_plot.pdf". We also provide the IPython Notebook "ptgm_plot.ipynb" with which this plot has been achieved. A detailed description of the content of the Excel sheets / CSV files follows below. Nodes sheet / ptgm_nodes.csv ---------------------------- This sheet / CSV file contains the list of the nodes (vertices) of the graph. The following columns are given: nid The node ID, an integer index used within this model to identify each node. osm_id If the node has a corresponding counterpart in OSM, we provide the OSM ID here. name If given, contains the name of the substation or power plant. type contains either "substation" or "plant", indicating the type of node. lat Latitude, geographical position of the node. lon Longitude, geographical position of the node. nominal_power_output In case of a power plant, the nominal power output. Unit: Megawatt (MW). population The estimated population supplied by this node. This estimate is obtained by a nearest-neighbor search for each city in the list of cities (see below) among the set of nodes. fraction_of_population Fraction of the total population of Pakistan being supplied by this node according to the nearest-neighbor estimate. fraction_of_total_consumed_power Fraction of the total Pakistani power consumption consumed at this node. Unit: Watthours (Wh). Links sheet / ptgm_links.csv ---------------------------- This sheet / CSV file contains the list of the links (edges) of the graph. The following columns are given: lid The link ID, an integer index used within this model to identify each link. osm_id If the link has a corresponding counterpart in OSM, we provide the OSM ID here. nid1 The ID of the node where the link starts. nid2 The ID of the node where the link ends. voltage The voltage level of this link. Currently only the 220 kV and the 500 kV voltage levels are considered in the model. Unit: Volts (V). cables The number of cables in the circuit. Typically a multiple of 3 due to 3-phasic AC circuits. wires The number of "wires" each cable is split into. Note that this information is so far missing from OSM data of Pakistan. length_direct The direct distance between start and end nodes. In the current version of the grid model, we do not consider the actual path lengths of the transmission lines, but instead just the direct point-to-point distance between the two end points. Unit: Kilometers (km). Cities sheet / ptgm_cities.csv ------------------------------ This sheet / CSV file contains the list of major Pakistani cities. This data has been used to estimate which share of power is consumed by each node in this model by exercising a simple nearest-neighbor search for each city among the set of nodes. In other words, we make the crude approximation that every city is provided with electrical energy by the nearest substation of the transmission grid. The following columns are given: cid The city ID, an integer index used within this model to identify each city. name The name of the city. population The number of citizens. province Name of the province in which this city is located. lat Latitude, geographical position of the city. lon Longitude, geographical position of the city. closest_distance Distance to the nearest node. Unit: Kilometers (km). closest_substation_index Index of the closest node. Industries sheet / ptgm_industries.csv -------------------------------------- This sheet / CSV file contains the list of major Pakistani industries. The following columns are given: iid The industry ID, an integer index used within this model to identify each industrial complex. name Name of the industry. city Name of the city at which the industry is located. closest_substation_index Index of the nearest node. States sheet / ptgm_states.csv ------------------------------ This sheet / CSV file contains the list of the Pakistani states (regions). The following columns are given: sid The state ID, an integer index used within this model to identify each state. name The name of the state. population The number of citizens of this state.
