Abstract: Unlike existing Energy Management System (EMS) which usually runs from a centralized server system at Power System Control Centre and operates large generating units and a transmission system via dedicated communication channels, this project aims to develop a low-cost, scalable, hierarchical transactive energy management system for use by load and supply aggregators of distribution systems. The loads and distributed energy resources are small in capacity but large in quantity. The proposed system considers three sets of inputs: supply side (e.g. intermittent PV system, bi-directional storage battery as supply, etc), demand side (e.g. variable controllable loads, storage battery as load, etc) and price fluctuations in real-time energy and reserve markets. A two-stage optimization technique is proposed for managing different types of battery energy storage systems. A model predictive control (MPC)-based controller scheme that is capable of coordinating hybrid energy storage systems and intermittent energy sources is validated via control-hardware-in-the-loop (CHIL) test setup in the lab. A decision support tool that can facilitate participation of loads in a demand response market is designed and proposed for use by load and supply aggregators.
