Load Frequency Control by Combining Direct Commands to Generators and Batteries with Real-time Price Presentations to Consumers

Abstract

We propose a novel real-time pricing method for load frequency control in a grid when there is a lot of wind power. We control batteries and thermal power plants simultaneously adjusting the electricity price for the owners of heat pump water heaters. In our method, the uncertainty due to indirectly controlling electricity consumption by price presentation is compensated by directly commanding batteries and thermal power plants. Our numerical simulation demonstrates that supply and demand are balanced and the load frequency in the grid is kept within the permissible range when wind power generation fluctuates rapidly in a short period.
