The article presents a new method for balancing electricity supply and demand in smart grids. By integrating wholesale (supply side) and retail (demand side) markets, a mechanism to set market prices was developed. This mechanism efficiently handles changing demand by introducing dynamic pricing for both generators and retailers. The researchers also created an algorithm to find the optimal balance between supply and demand. Their experiments show that this new approach can manage unpredictable demand, support cost-effective electricity generation, and help maximize profits for retailers.
