To implement a multi-microgrid system in ns-3 consists of numerous steps. NS-3 is basically used for simulating the network so we need to simulate the communication phase of the microgrid systems. Here are the basic steps on how to proceed with this:
Step-by-Step Guide to Implement Multi-Microgrid in ns-3
- Set Up Your Development Environment:
- Install ns-3 on your system. You can follow the official ns-3 installation guide.
- Make sure you have a working knowledge of C++ as ns-3 scripts are written in C++.
- Understand the Requirements:
- Define the components of your multi-microgrid system, such as nodes representing microgrids, controllers, communication protocols, and network topology.
- Identify the specific communication protocols that will be used (e.g., TCP, UDP).
- Design the Network Topology:
- Plan your network topology, including how the microgrids are connected and how they communicate with each other.
- You can use existing examples in ns-3 as a starting point. For instance, you might look at examples involving mesh networks or ad-hoc networks.
- Create Nodes and Network Devices:
- Create nodes representing each microgrid and controller in your system.
- We Install network devices on these nodes to enable communication.
NodeContainer microgrids;
microgrids.Create(numberOfMicrogrids);
NodeContainer controllers;
controllers.Create(numberOfControllers);
NetDeviceContainer devices;
// Set up network devices, such as Wifi or CSMA devices
- Install Internet Stack:
- Install the Internet stack on the nodes to enable IP-based communication.
InternetStackHelper internet;
internet.Install(microgrids);
internet.Install(controllers);
- Assign IP Addresses:
- Assign IP addresses to the nodes.
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
- Implement Communication Protocols:
- Implement the communication protocols between the microgrids and controllers. This might involve setting up TCP/UDP sockets, sending packets, and handling responses.
// Example of setting up a UDP server on a controller
UdpServerHelper udpServer(port);
ApplicationContainer serverApp = udpServer.Install(controllers.Get(0));
serverApp.Start(Seconds(1.0));
serverApp.Stop(Seconds(10.0));
// Example of setting up a UDP client on a microgrid
UdpClientHelper udpClient(interfaces.GetAddress(0), port);
udpClient.SetAttribute(“MaxPackets”, UintegerValue(320));
udpClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));
udpClient.SetAttribute(“PacketSize”, UintegerValue(1024));
ApplicationContainer clientApp = udpClient.Install(microgrids.Get(0));
clientApp.Start(Seconds(2.0));
clientApp.Stop(Seconds(10.0));
- Simulate Microgrid Behavior:
- Simulate the behavior of microgrids, such as energy production, consumption, and sharing information with other microgrids or the controller.
Simulator::Schedule(Seconds(2.0), &MicrogridFunction, microgrids.Get(0));
- Run the Simulation:
- Set the simulation start and stop times, and run the simulation.
Simulator::Run();
Simulator::Destroy();
Example Code Snippet
The below is a given sample snippet to complete the script for multi-microgrid system in ns-3 environment.
#include “ns3/core-module.h”
#include “ns3/network-module.h”
#include “ns3/internet-module.h”
#include “ns3/point-to-point-module.h”
#include “ns3/applications-module.h”
using namespace ns3;
int main(int argc, char *argv[]) {
NodeContainer microgrids;
microgrids.Create(3);
NodeContainer controllers;
controllers.Create(1);
PointToPointHelper pointToPoint;
pointToPoint.SetDeviceAttribute(“DataRate”, StringValue(“5Mbps”));
pointToPoint.SetChannelAttribute(“Delay”, StringValue(“2ms”));
NetDeviceContainer devices;
devices = pointToPoint.Install(microgrids.Get(0), controllers.Get(0));
InternetStackHelper stack;
stack.Install(microgrids);
stack.Install(controllers);
Ipv4AddressHelper address;
address.SetBase(“10.1.1.0”, “255.255.255.0”);
Ipv4InterfaceContainer interfaces = address.Assign(devices);
UdpServerHelper udpServer(9);
ApplicationContainer serverApp = udpServer.Install(controllers.Get(0));
serverApp.Start(Seconds(1.0));
serverApp.Stop(Seconds(10.0));
UdpClientHelper udpClient(interfaces.GetAddress(1), 9);
udpClient.SetAttribute(“MaxPackets”, UintegerValue(320));
udpClient.SetAttribute(“Interval”, TimeValue(Seconds(0.1)));
udpClient.SetAttribute(“PacketSize”, UintegerValue(1024));
ApplicationContainer clientApp = udpClient.Install(microgrids.Get(0));
clientApp.Start(Seconds(2.0));
clientApp.Stop(Seconds(10.0));
Simulator::Run();
Simulator::Destroy();
return 0;
}
As we discussed earlier about how the multi-microgrid system will perform in ns-3 environment and we help to provide further information about how the multi-microgrid system will adapt in different environments.
