Transactive energy (TE) is the economic and control methods used to manage the exchange of energy within an existing power system. It is a concept that is used to improve the efficiency and reliability of the power system. This TE network structure allows for communication so that all levels of energy generation and consumption can interact with one another and is exponentially more complex than traditional control of generating sources. Register now to gain an understanding of the fundamentals of TE and real-world applications that will create an intelligent and interactive future for the industry.
