Analysis of System Value Evolution Trends of Energy Storage in Decarbonization Process

With the continuous expansion of the scale of renewable energy installation,the demand for energy storage has increased significantly.However,there are significant differences in the value of energy storage in different scenarios,and the phenomenon of diminishing marginal benefits of energy storage is becoming more apparent.Therefore,themulti-dimensional value evolution trend of energy storage has become a key issue.This study selects indicators from three dimensions of energy storage:low-carbon emission reduction,smoothing wind and solar power fluctuations,and saving generation costs,quantifying the economic,environmental,and technical values of energy storage.This forms a quantitative evaluation system for energy storage value.By comparing the calculated system values under different energy storage capacities,the marginal value evolution trend of energy storage is obtained.Meanwhile,considering factors such as the utilization rate of renewable energy,the change in energy storage value under different scenarios is analyzed.The results show that the value of long-duration energy storage is significantly affected by the energy storage capacity.Specifically,when the charge-discharge efficiency of longduration energy storage reaches 0.6 or above,the system value increases significantly.Additionally,appropriately reducing the cost of energy storage capacity also helps to improve its system value.

Influence of architectural heritage on the identity and present-day value of American-designed universities’campuses in Asia

In this study,through case studies of campus architectural heritage,the preservation of architectural heritage on campuses is explored.In addition,the effects of architectural heritage preservation on the identity of campuses are investigated,and the corresponding effects on present-day value and spatial experience are analysed.The case studies involve early campuses planned in East Asia by Henry Murphy,and they feature American designs and building styles.In this study,first,the characteristics of the campuses planned by Henry Murphy are analysed.Next,the characteristics of the preserved architectural heritage at Chosen Christian College are analysed.Finally,with a focus on the preservation of architectural heritage at Shanghai College,the value of architectural heritage and the spatial experience associated with campus development are analysed.Chosen Christian College focused on maintaining the authenticity of buildings,and Shanghai College attempted to consolidate the identity of the campus through maximizing the spatial experience of the architectural heritage group and preserving architectural heritage.Thus,Shanghai College was more influenced by Henry Murphy’s master plan in the development and growth of the campus,and tried to carry on the design concept of the architect and the image of the campus.Conversely,Chosen Christian College was able to retain its original design over nearly a century with the use of all-stone buildings,as Henry Murphy proposed,but no significant trace of the early general plan remains.
