This paper presents a strategy based on the hierarchical rolling horizon control, also called model predictive control (MPC), for efficiently managing hydrogen-energy storage system (HESS) within an islanded wind-solar microgrid. An electrolyzer uses electricity generated from renewable sources to produce clean hydrogen, which is then re-electrified by fuel cell as needed meet microgrid's loads. The main contribution lies in incorporation of multiple hydrogen tanks HESS, distinguishing it existing literature, typically focuses single tank. HESS enables large volumes long-term use, allowing microgrid operate autonomously without interaction with utility grid. In order ensure optimal performance, selection most suitable device operation at each time-step crucial. proposed takes into account economic and operational costs, degradation aspects, physical constraints while simultaneously ensuring tracking reference demands highest priority smoothing out variations energy sources. Numerical simulations lab-scale setup demonstrate that controller effectively manages thus satisfying optimizing even when deviations occur between predicted real-time scenarios. Furthermore, inclusion allows both mitigate fluctuations power load demand.

Optimizing long-term park-level integrated energy system through multi-stage planning: A study incorporating the ladder-type carbon trading mechanism

Results in Engineering, Год журнала: 2024, Номер 22, С. 102107 - 102107

Опубликована: Апрель 8, 2024

The integrated energy system is widely acknowledged as an effective method for advancing the adoption of renewable sources and reducing carbon emissions. To address economic issues caused by inconsistency between traditional single-stage planning capacities park-level (PIES), long-term model proposed, which consists multi-stage divisions incorporates ladder-type trading mechanism. utilizes long-term, approach to determine optimal installed capacity equipment. Meanwhile, mechanism conducted considering relationship actual emissions, emission quotas, cost. study assesses impact mechanisms various stage on feasibility PIES its ability reduce results indicate that compared fixed price strategies, implementation increases costs 0.15 %–0.18 %, but reduces emissions 0.36 %–0.6 %; number stages increases, significantly decrease, lifecycle also decrease. Compared planning, decrease 14.6 % 15.17 at K = 15; when baseline set 0.5 yuan/kg growth rate 0.5, values cost are achieved. In conclusion, this serves references strategic implementations PIES, emphasizing importance efficiency low-carbon practices in line with system's development sustainability objectives.
