Three operation modes of self-adaption, FEL and FTL are comprehensively considered to optimize the configuration of integrated energy station. On this basis, the sensitivity of heat-to-electric ratio (HPR) of CHP units and electric storage to the planning results are analyzed.
Taking the minimization of annualized cost as the objective function, as well as introducing environmental penalty cost, a bi-level optimal configuration model of integrated energy station is established to realize the collaborative optimization in the planning and operation stages.
The planning results of integrated energy station are evaluated based on system dynamics (SD), which has certain guidance for the actual project. Operation modes of combined heat and power (CHP) units are closely related to the economic benefits of energy application in integrated energy station.
Structure of the integrated energy station The integrated energy station is aiming to self-production and self-sales of renewable energy on the premise of meeting the local demand for electricity, heat and cooling through the full utilization of wind and solar output.
Both the ES and the HPR of CHP units have an impact on the planning of integrated energy station. The increase of HPR raises the upper limit of the CHP units thermal power output. The ES can improve the economy of integrated energy station from 0.4% to 8%.
Integrated energy station can supply energy to end-users cover, production, conversion and storage facilities. However, due to the uncertainties of renewable sources and terminals as well as resource endowments in different places, the construction of multi-energy system needs to be tailored to local conditions.
