How to start Smart Grid Networks Projects using NS2

To start an Smart Grid Network project using Network Simulator 2 (NS2) has been including their designing the network which helps for the management of electricity distribution, tracking and communication among the smart meters, energy sources, and control centers. Smart grids enable two-way communication and control among the electricity providers and consumers, making them an ideal candidate for replication in NS2.

Though NS2 is not integrally create for Smart Grid simulation, it can be adjusted to replicate the features like as communication among smart meters, grid management systems, energy distribution, and use the protocols such as Internet of Things (IoT) devices for real-time tracking.

Step-by-Step Guide to Start a Smart Grid Project in NS2

Step 1: Understand Smart Grid Network Components

Previously the replications are splitting core to recognize the main modules for the Smart Grid:

  1. Smart Meters: Devices at homes or businesses which gather the data on energy usage.
  2. Grid Operators: It centralized the systems which track the control for distribution of energy.
  3. Communication Networks: Two-way communication networks for instance cellular, Wi-Fi, LPWAN) which transmit the real-time data among their smart meters and grid operators.
  4. Distributed Energy Resources (DERs): The other renewable sources for energy which interact by the grid and transfer the Solar panels, wind turbines.
  5. Demand Response: The demand mechanisms in which the consumers can adapt their energy usage in response for grid environments.
  6. Control and Automation: The smart grid structure which assign the remote control and automation for grid operations.

Step 2: Install NS2

If NS2 is not previously installed, we will require installing the system. We can download and install the NS2 from its official website, or use package managers for instance apt for Ubuntu to install it.

We validate the installation, kind the following command in the terminal:

ns

This should start the NS2 command prompt.

Step 3: Define Your Smart Grid Simulation Scenario

Designed for the replicating a Smart Grid Network, we can set the following:

  • Smart Meters: The nodes are which replicate the smart meters, in which the data is gathered and forward for the central control system.
  • Base Station / Control Center: The node which receives the data from smart meters and creates a decision according to which data for instance adjusting power flow or responding to demand.
  • Communication Protocols: Use protocols for communicate the technologies like as Wi-Fi, Zigbee, LPWAN, or Cellular networks to distribute the data from meters to the control center.

Designed for simplicity, let’s concentrate on a basic smart grid scenario by smart meters and control center using the Wi-Fi communication.

Step 4: Create the Simulation Scenario in NS2

Here is a simple replication setting for a Smart Grid Network in NS2.

Example: Smart Grid Network Simulation with Smart Meters and a Control Center

# Create the simulator object

set ns [new Simulator]

# Create nodes (Smart Meter, Base Station / Control Center)

set control_center [$ns node]  ;# Control Center node (Grid Operator)

set smart_meter1 [$ns node]    ;# Smart Meter 1

set smart_meter2 [$ns node]    ;# Smart Meter 2

set smart_meter3 [$ns node]    ;# Smart Meter 3

# Define the communication links between Smart Meters and Control Center

$ns duplex-link $smart_meter1 $control_center 10Mb 50ms DropTail

$ns duplex-link $smart_meter2 $control_center 10Mb 50ms DropTail

$ns duplex-link $smart_meter3 $control_center 10Mb 50ms DropTail

# Define mobility models (for simplicity, all nodes are static)

$ns node-config -motion “fixed” -x 0 -y 0 -z 0   ;# Control Center (static)

$ns node-config -motion “fixed” -x 500 -y 500 -z 0 ;# Smart Meter 1

$ns node-config -motion “fixed” -x 600 -y 600 -z 0 ;# Smart Meter 2

$ns node-config -motion “fixed” -x 700 -y 700 -z 0 ;# Smart Meter 3

# Set up communication: Use UDP agents to simulate data exchange

set udp_control_center [new Agent/UDP]

set udp_meter1 [new Agent/UDP]

set udp_meter2 [new Agent/UDP]

set udp_meter3 [new Agent/UDP]

# Attach UDP agents to the nodes

$ns attach-agent $smart_meter1 $udp_meter1

$ns attach-agent $smart_meter2 $udp_meter2

$ns attach-agent $smart_meter3 $udp_meter3

$ns attach-agent $control_center $udp_control_center

# Define traffic applications (Simulate data transfer from smart meters to control center)

set cbr_meter1 [new Application/Traffic/CBR]

$cbr_meter1 attach-agent $udp_meter1

$cbr_meter1 set packetSize_ 512

$cbr_meter1 set interval_ 0.1

$cbr_meter1 set random_ 1

set cbr_meter2 [new Application/Traffic/CBR]

$cbr_meter2 attach-agent $udp_meter2

$cbr_meter2 set packetSize_ 512

$cbr_meter2 set interval_ 0.1

$cbr_meter2 set random_ 1

set cbr_meter3 [new Application/Traffic/CBR]

$cbr_meter3 attach-agent $udp_meter3

$cbr_meter3 set packetSize_ 512

$cbr_meter3 set interval_ 0.1

$cbr_meter3 set random_ 1

# Start the data transfer at time 1.0 and stop at time 5.0

$ns at 1.0 “$cbr_meter1 start”

$ns at 5.0 “$cbr_meter1 stop”

$ns at 1.0 “$cbr_meter2 start”

$ns at 5.0 “$cbr_meter2 stop”

$ns at 1.0 “$cbr_meter3 start”

$ns at 5.0 “$cbr_meter3 stop”

# Set finish time for simulation

$ns at 6.0 “finish”

# Define finish procedure

proc finish {} {

global ns

$ns flush-trace

exit 0

}

# Run the simulation

$ns run

Explanation of the Script:

  1. Simulator Setup:
    • set ns [new Simulator]: Build the NS2 replicator in an object.
  2. Node Creation:
    • set control_center [$ns node]: Generates the Control Center node, that receives the data from smart meters.
    • set smart_meter1 [$ns node], set smart_meter2 [$ns node], set smart_meter3 [$ns node]: Makes the Smart Meter nodes.
  3. Network Links:
    • duplex-link: Generates the bidirectional communication links among the smart meters for the control center by 10 Mbps bandwidth and 50 ms delay.
  4. Mobility Model:
    • The nodes are static in this simple environment. We can alter the mobility models and replicate the mobile nodes for sample electric vehicles or mobile grid stations.
  5. Communication:
    • UDP: The communication among the smart meters for the control center is replicating the UDP agents.
    • CBR Traffic: The Constant Bit Rate (CBR) traffic application is used to replicate the data generation for periodic from the smart meters to the control center.
  6. Traffic Flow:
    • The congestion starts at time 1.0 and ends at time 5.0. This replicates the continuous for gathered the data from the meters.
  7. Finish Procedure:
    • The replication is setting the drop at 6.0, and the trace data is flushed.

Step 5: Run the Simulation

Store the replication script as smart_grid_simulation.tcl and perform the NS2:

ns smart_grid_simulation.tcl

The NS2 will create a trace file (*.tr) that logs all the movements and transmission. This trace file can be study to estimate the performance for the smart grid network.

Step 6: Analyze the Results

We can extract the information from the trace file using AWK to check the packet reception, delays, and other metrics:

awk ‘{ if ($1 == “r”) print $0 }’ tracefile.tr > received_packets.txt

We can also envision the outcomes using Xgraph to plot parameters metrices such as throughput, delay, and packet loss:

xgraph tracefile.tr

Step 7: Explore Further

Next execute the simple replication; we can research by advanced features of a Smart Grid:

  1. Communication Technologies:
    • Research by various communication technologies for sample Zigbee, Wi-Fi, LPWAN.
  2. Demand Response:
    • Demand responses are replicate in which the consumers can adapt energy usage according to their control center commands.
  3. Distributed Energy Resources (DERs):
    • Design the incorporate for renewable energy sources such as solar panels, wind turbines in the smart grid.
  4. Energy Management:
    • Execute the energy management procedures for optimal distribution and storage.
  5. Security:
    • Increase the security protocols and prevent the smart grid communications from attacks such as man-in-the-middle or DoS attacks.
  6. Smart Grid Optimization:
    • Optimization uses the procedures for load balancing, network optimization, and energy distribution.

Step 8: Documentation and Reporting

  • Topology Diagram: It demonstrates the smart grid network setting for instance meters, control center, communication connection.
  • Traffic Protocols: The document provides the protocols used for sample UDP, CBR.
  • Analysis: It offers the results for throughput, latency, energy consumption, etc., according to the replication
  • Use Cases: Debate the applications such as real-time monitoring, energy management, and demand response.
