Peak electricity demand is a big issue for the power grid. Instead of just adding more capacity, we can also manage how much electricity we use at home. By shifting some tasks to off-peak times, we can reduce peak demand and save money on our electricity bills. A study used a system called Matlab/Simulink to see how this could work for homes. They found that managing when we use electricity can help lower peak demand and save money. They also looked at different types of household appliances to see how they use electricity.
