20.500.12556/RUL-166997 Enhancing power system reliability through demand flexibility of grid-interactive efficient buildings a thermal model-based optimization approach The paper evaluates the impact of grid-interactive efficient buildings (GEBs) on power system reliability. To achieve this, a single-zone thermal model of a building is developed, allowing for the simulation of indoor temperature dynamics based on the characteristics of the building envelope and internal thermal mass. The potential of GEBs to adjust their electric consumption, recognized as demand flexibility, is integrated into the direct optimization of reliability indices, specifically Loss of Load Expectation (LOLE) and Expected Energy Not Supplied (EENS). The analysis is conducted using the proposed optimization model in two distinct case studies. In the first scenario, households do not support the power system and only optimize their energy consumption for heating and cooling. In the second scenario, households provide available demand flexibility of GEBs to the power system to enhance reliability. This demand flexibility is constrained by the need to maintain indoor temperature within limits that ensure comfortable use of the space. The analysis highlights the potential of GEBs to improve power system reliability by reducing LOLE and EENS. The primary scientific contribution of this research is the development of an optimization model that incorporates a thermal model of GEBs without assuming a generic demand flexibility for the buildings. expected energy not supplied linear programming loss of load expectation optimization power system reliability thermal model of a building pričakovana nedobavljena energija linearno programiranje pričakovani izpad pokrivanja porabe optimizacija zanesljivost elektroenergetskega sistema termični model stavbe true false true Angleški jezik Slovenski jezik Članek v reviji 2025-02-03 11:12:56 2025-02-03 11:13:00 2025-02-04 09:35:26 0000-00-00 00:00:00 2025 0 0 12 str. art. 125045 Vol. 381 1 Mar. 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.311 1872-9118 10.1016/j.apenergy.2024.125045 224863747 1-s2.0-S0306261924024292-main.pdf 1-s2.0-S0306261924024292-main.pdf 1 DD43432942C64E6ED5F4D6BCFA643159 b2a2423046c02b3d418ec039d88f66b5f21ca897205da8b7d471d06d16824371 d2067e44-e216-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199071 https://www.sciencedirect.com/science/article/pii/S0306261924024292 1 9d14528b-e216-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=199070 Fakulteta za elektrotehniko 0 0 0
