Abstract
Integrated electrical and heating systems(IEHS) are
drawing huge attention because of their cost-effective and flexible
operational capabilities. Optimal dispatch of renewable units
in an IEHS is challenging because of their intermittent and
stochastic nature. Uncertainties in the renewable energy source
(RES) forecast, electrical, and thermal loads can cause voltage
and temperature violations compromising the operational secu rity of the system. In this paper, a rule-based dynamic dispatch
is proposed to handle the increasing levels of uncertain RES
and ensure the system’s security. A chance-constrained (CC)
co-optimization algorithm considering the uncertain loads and
RES is developed. In the proposed method, electric boiler power
and curtailment of RES are dynamically dispatched to reduce
operational costs and network losses. The developed method is
tested on the IEEE 15 bus distribution system and UK Generic
Distribution System (UKGDS) 95 bus test system models. The
results show that the proposed method significantly reduces the
voltage deviations and temperature violations compared to the
deterministic case.
