Forecast uncertainties pose a considerable challenge to the success of model predictive control (MPC) in buildings. Numerous possibilities for considering forecast MPCs are available, but an in-depth comparison is lacking. This paper compares two main approaches consider uncertainties: robust and stochastic MPC. They benchmarked against deterministic MPC with perfect forecast. The utilize holistic building reflect modern smart homes that include photovoltaic power generation storage, thermally controlled loads, appliances. Real-world data used identify thermal model. performance various controllers investigated under three levels uncertainty models different envelope performance. For highly insulated building, achieves satisfactory comfort when error medium or low, compromised high errors. In poorly at Compared MPC, increases electricity cost by up 4.5% provides complete temperature constraint satisfaction while less than 1% fulfills requirements.

Opening of Ancillary Service Markets to Distributed Energy Resources: A Review

Energies, Год журнала: 2023, Номер 16(6), С. 2814 - 2814

Опубликована: Март 17, 2023

Electric power systems are moving toward more decentralized models, where energy generation is performed by small and distributed plants, often from renewables. With the gradual phase out fossil fuels, however, Distribution Energy Resources (DERs) expected to take over in provision of all regulation services required operate grid. To this purpose, opening national Ancillary Service Markets (ASMs) DERs considered an essential passage. In order allow transition happen, current opportunities barriers market participation must be clearly identified. work, a comprehensive review provided state-of-the-art research on DER integration into ASMs. The topic at hand analyzed different perspectives. First, situation main trends regarding reformation processes ASMs get clear picture evolutions adjustment future, according scientific community. Then, focus moved strategies adopted aggregators for effective control coordination DERs, exploring challenges posed uncertainties affecting problem. Coordination schemes between transmission distribution system operators, implications grid infrastructure operation planning, also investigated. Finally, deepens capabilities technologies perform needed actions.

Digitalization and sector coupling enable companies to turn into flexumers. By using the flexibility of their multi-energy system (MES), they reduce costs carbon emissions while balancing electricity grid. However, identify necessary investments in energy conversion storage technologies leverage demand response (DR) potentials, need assess value flexibility. Therefore, this study quantifies a production company's MES by optimizing synthesis, design, operation decarbonizing considering self-consumption optimization, peak shaving, integrated DR based on hourly prices emission factors (CEFs). The detailed case beverage company northern Germany considers vehicle-to-X electrical industrial forklifts, power-to-heat multiple temperatures, wind turbines, photovoltaic systems, systems (thermal, electrical, hydrogen). We propose apply novel data-driven metrics evaluate intensity price-based CEF-based DR. results reveal that usage reduces decarbonization (by 19%–80% depending removal prices), total annual costs, operational footprint, energy-weighted average CEFs, fossil dependency. also suggest net-zero requires flexibility, which, an economic case, is provided combination different flexible complement each other. While depends various market consumer-specific such as or prices, highlights importance for MESs.
