Energy Internet(EI) as the future solution to the shortage of fossil energy and the worsening environment problem, is becoming the hotspot and the trend of the research. Firstly, the paper expounds the connotation and features of Energy Internet, and put forward the new requirements of the Energy Internet system energy management with four elements, namely the grid structure, consumptive pattern, measuring method and research perspective. Secondly, summarizes the related research at home and abroad of Energy Internet system energy management on the aspect of system structure design, robust modeling of energy management and optimization algorithm design. Finally, the future issue of Energy Internet system energy management research is prospected.

Energy Local Area Network(ELAN) is the core component of the Energy Internet(EI), including wind power generation, energy storage equipment, electric vehicles and many kinds of intelligent loads. It can be used as a scheduling unit to accept EI layer control system. Complex structure, multiple correlation and strong coordination requirements have been the major obstacle to the realization of the accurate and timely optimization scheduling of ELAN. First of all, we talk about the composition of ELAN, physical structure and relationship between constitute factors. Secondly, Based on drawing the causality diagram and system flow chart, we built the SD model of ELAN. Thirdly, considering from the two aspects of structure and behavior model, we test and verify the model reliability and validity through the structure applicability test, structure consistent test, behavior applicability test and behavioral consistency test. Finally, based on the model correct test, we carried out the regular test and the policy simulation test, and the research conclusions of this paper are presented.

This work demonstrates that in situ formation of carbonate layer on the surface of Ba0.5Sr0.5Co0.8Fe0.2O3-δ(BSCF)obtained by exposure to CO2 during heating between 500℃ and 700℃ can provide enhanced oxygen evolution reaction(OER)performance and durability in an alkaline solution relative to the original *** temperatures,i.e., 500℃,600℃,and 700℃ were chosen to perform the CO2 thermal treatment,resulting into BSCF-500,BSCF-600,and BSCF-700 *** OER was enhanced in the order of BSCF-500< BSCF-700 < BSCF-600. BSCF-600 showed the best OER performance, i.e., a low overpotential of 0.36 V required to attain 10 mA cm^-2 current density as well as a mass activity of 74.14 Agcmcat-1 and a specific activity of 5.04 mA cmcat-2 at an overpotential of 0.4 V. The OER performance durability of BSCF-600 was highlighted by its ability to maintain a stable potential of around 1.61 V vs. RHE (RHE: reversible hydrogen electrode) when charged at a constant current density of 10 mA cm^-2 throughout the 800 min continuous chronopotentiometry test. The enhanced OER performance for BSCF-600 relative to the original BSCF is attributed to three factors:(i) higher electrochemically active surface area;(ii) faster charge transfer rate and higher electrical conductivity;and (iii) modified oxidation state of cobalt ions. The formation of thin carbonate layer in BSCF-600 appears to suppress the durability issue observed in BSCF.
