Building energy flexibility plays a critical role in demand-side management for reducing utility costs building owners and sustainable, reliable, smart grids. Realizing tropical regions requires solar photovoltaics storage systems. However, quantifying the of buildings utilizing such technologies has yet to be explored, robust control sequence is needed this scenario. Hence, work presents case study evaluate controls operations net-zero office Singapore. The utilizes data-driven quantification workflow employs novel model predictive (MPC) framework based on physically consistent neural network (PCNN) optimize flexibility. To best our knowledge, first instance that PCNN applied mathematical MPC setting, stability system formally proved. Three scenarios are evaluated compared: default regulated flat tariff, real-time pricing mechanism, an on-site battery (BESS). Our findings indicate incorporating into could more beneficial leverage decisions than flat-rate approach. Moreover, adding BESS PV generation improved self-sufficiency self-consumption by 17% 20%, respectively. This integration also addresses mismatch issues within framework, thus ensuring reliable local supply. Future research can proposed PCNN-MPC different types.

Energy communities (ECs) play a crucial role in promoting the adoption of renewable energy resources and establishing local markets for sharing trading among end-users (e.g., residential buildings) prosumers (plus buildings). However, since are connected to distribution grids, their transactions can sometimes lead reversed power flows potential quality issues, such as over-voltage. This paper introduces concept Virtual Communities (VECs) coordination mechanism designed align goals ECs with flexibility requirements grid operator. The smart buildings employs Particle Swarm Optimization algorithm identify optimal VEC configurations that effectively manage activities adhere constraints. tool's performance is evaluated focus on voltage levels imbalance factors across various case studies. results demonstrate building efficiently mitigates overvoltage imbalances by implementing VECs, all while causing minimal disruption opportunities. significant importance, providing its own not economically viable. Therefore, this offers valuable win-win solution both flexibility.
