Summary: A flexibility estimation model is proposed to evaluate the immediate aggregate flexibility response in a day-ahead scheme. The model schedules appliances and calculates aggregated flexibility based on energy and flexibility prices. It uses an alternative flexibility scenario approach to evaluate immediate flexibility available for the next 15 minutes or 4 hours. New flexibility constraints are introduced for specific appliances, and the model is tested under different energy price schemes to observe the influence on flexibility offered.

Summary: This study investigates the demand-side flexibility potential of Singapore's building stock and explores how it can be realized through demand-side bidding. Through a case study in Singapore's Downtown Core district, factors such as building types, cooling load, and occupancy schedule were found to impact DSF potential. Demand-side bidding, compared to centralized dispatch, can help consumers utilize their energy resources more effectively, reducing total electricity costs.

Summary: Residential demand side management (DMS) is an effective tool for maintaining network balance, but privacy concerns related to user personal consumption data have hindered its widespread adoption. This paper proposes a privacy-preserving aggregation algorithm based on additive random shares and a combination of symmetric and asymmetric key cryptography methods. The algorithm is compared with other techniques such as additive homomorphic encryption (AHE) and state-of-the-art MPC protocols. The results show that while generic techniques like homomorphic encryption are computationally expensive, MPC approaches provide better performance and resilience for large networks. The proposed additive random shares algorithm is considered the most balanced choice for DSM, offering good performance, simpler information flow, and the ability to add redundant intermediary parties for enhanced resilience.

Summary: A multi-leader-follower game (MLFG) is a bilevel problem where the upper and lower levels are defined by Nash non-cooperative competition among the leaders and the followers. Although complex, MLFGs are perfect models to describe hierarchical interactions among actors in real-life problems. In this study, we focus on a class of MLFGs that model demand-side management in an electricity market. Our goal is to propose innovative approaches to efficiently tackle this difficult problem.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
