Quantized event-driven simulation for integrated energy systems with hybrid continuous-discrete dynamics

Effective simulation methods are becoming critically essential for the analysis of integrated energy systems (IESs) to reveal interactions multiple carriers. The incorporation various technologies and numerous controllers make IES a heterogeneous system, which poses new challenges methods. This paper focuses on an with hybrid continuous-discrete properties characteristics. First, modified third-order quantized state system (MQSS3) method is proposed district heating (DHSs), in (QSS) time-discretized integration efficiently manage discrete control actions. Second, event-driven framework established integrate MQSS3 into electricity-heat (EH-IES). enables adoption most suitable models algorithms different accommodate IES. Case studies EH-IES maximum 80% PV penetration 210 buildings demonstrate that dynamic between DHS power distribution network accurately illustrated by methods, indicates highest efficiency. It also demonstrated results flexibility from can be utilized as demand-side resource support operation aspects such consuming surplus generations.
