Abstract
The rapidly transforming electric power grid faces unprecedented challenges due to misaligned infrastructure, alternative energy sources, and high aggregate peak time usage. Considering this issue, the power systems community has widely recognized the value of demand response (DR) resources in improving the operational efficiency of the emerging power grid. However, a vast majority of engagement from customers remains untapped. This dissertation develops enablers for encouraging a higher level of demand-side participation in the power distribution systems. Towards this goal, we make the following four major contributions in this dissertation.
First, we develop a controller for the buildings’ energy management. The controller minimizes the net energy cost usage by scheduling the energy consumption of the heating, ventilation, and air conditioning (HVAC) system and employing heterogeneous energy supply sources such as battery energy storage system (BESS) while satisfying the comfort level of the building’s occupants in a computationally tractable manner. A robust HVAC system controller is also proposed to obtain optimal control actions in the presence of the model uncertainties and disturbances.
Second, we design amenable Critical Peak Rebate (CPR) contracts for residential customers to incentivize their participation in DR programs. These contracts allow the energy provider a short-term direct load control of individual HVAC systems in exchange for monetary incentives. Our contact design algorithm maximizes the utility of the energy provider while simultaneously satisfying customers’ energy usage preferences.
Third, we propose an approach for the profit-seeking load-serving entity (LSE) to bid the aggregated demand flexibility into the wholesale market. The proposed approach considers the heterogeneity of DR resources and the distribution system’s operating constraints in the LSE’s bidding process. The goal is to maximize the expected revenue of the LSE by scheduling DR resources when constructing economic bids for the day-ahead wholesale market.
Fourth, we present a comprehensive study of the centralized and transactive coordination mechanisms for supply and demand resources at the distribution system level. These coordination methods are compared using different metrics under several test scenarios. The economic impacts of these approaches on different market participants and the wholesale market are detailed.
