Demand Side Management in Large-Scale Buildings with Intraday Impact

The 15 minute intraday electricity market in Europe is approaching, and the market is vital to maintain grid stability in a growing landscape of renewable energy. By facilitating flexible and cross-border trade, it supports the sustainability goals of the EU while improving energy security and efficiency on the continent. The buildings are responsible for approximately 40 % of global energy consumption with remarkable amounts of the buildings already using renewable energy sources to make it more complicated. The situation with the 15-minute market can be highly volatile, reflecting immediate demand and supply changes. For instance, sudden weather changes that affect solar or wind generation can drive significant price fluctuations. redistribution of energy sources and suppliers results in high volatility in the energy market-from extremely high to even negative prices. This volatility may significantly impact large consumers with especially complex dynamic operations and multiple stakeholders such as large-scale buildings. Consequently, the paper presents detailed case studies during the day and night on the example of several commercial buildings in Estonia with a one-second measurement interval of HVAC equipment. The technical readiness of buildings to handle flexibility towards the 15-minute market will also be studied.
