TITLE: Demand Side Management with Packetized Energy and Its Integration to Provide Regulation Reserve ABSTRACT: Demand side management is of great interest in the field of smart grid. In this prospectus, we propose a novel energy distribution protocol with the idea of electric packet that is inspired by the success of packet switch in communication networks. We consider the new distribution protocol when the building operator has different level of information from local appliances. When binary information regarding the request or withdrawal of electric packets presents, we show that we can control the appliances arrival rate by designing the duration of electric packet. Energy distribution with electric packet guarantees a fairness energy delivery when limited amount of electricity is provided to a large group of appliances. When short duration of packet is provided, each appliance waits for a short duration to get packet authorization and the expected waiting time to get the desired number of packet remains the same. When continuous information regarding the appliances states is available to the operator, we show that the building operator can determine the average consumption with the aggregated information from local appliances. In addition, energy distribution with electric packet is able to reduce the random aggregation of load and smooth the consumption to have minimum variance. Next, we discuss the scenario when smart buildings participate into the electric market to provide regulation reserve via direct control of appliances’ set point. We propose a two level feedback system between the building operator and the independent system operator (ISO) and investigate the limitation of providing both long and short term regulation reserve that is characterized by the parameters from the buildings. This limitation gives an upper bound on the amount of energy sold in the market. Furthermore, we formulate a real time optimization problem such that the ISO dispatches signals in an optimized way to reduce real time spinning generation.
