Open Smart Grid Protocol is a way for different electronic devices, like machines or appliances, to connect with each other on a computer network. It makes it easier for these devices to communicate, share information and work together. For example, a device might ask for power to light up or make something run. The Open Smart Grid Protocol helps it to get the power from the network so it can do its job. Think of it like a network of roads that all the devices can use to get the power they need.
