Regional Renewable Energy Optimization Based on Economic Benefits and Carbon Emissions

With increasing renewable energy utilization,the industry needs an accurate tool to select and size renewable energy equipment and evaluate the corresponding renewable energy plans.This study aims to bring new insights into sustainable and energy-efficient urban planning by developing a practical method for optimizing the production of renewable energy and carbon emission in urban areas.First,we provide a detailed formulation to calculate the renewable energy demand based on total energy demand.Second,we construct a dual-objective optimization model that represents the life cycle cost and carbon emission of renewable energy systems,after which we apply the differential evolution algorithmto solve the optimization result.Finally,we conduct a case study in Qingdao,China,to demonstrate the effectiveness of this optimizationmodel.Compared to the baseline design,the proposedmodel reduced annual costs and annual carbon emissions by 14.39%and 72.65%,respectively.These results revealed that dual-objective optimization is an effective method to optimize economic benefits and reduce carbon emissions.Overall,this study will assist energy planners in evaluating the impacts of urban renewable energy projects on the economy and carbon emissions during the planning stage.

Research on the Reconstruction and Renewal of the Landscape Space of Industrial Sites in Post-industrial Era:A Case Study of Guangzhou Zilintang Art Town

With the rapid development of urbanization,traditional old industrial areas can not cope with the impact of the new wave of urbanization and have been abandoned,demolished and remodeled.Solving the pollution problem of industrial wasteland has become an important part of urban renewal research.Based on the development of industrial sites,the paper discusses the design principles and methods of industrial sites.Through the case analysis of the industrial site of Guangzhou Zilintang Art Town,the paper excavates the deep cultural deposits in the post-industrial era and analyzes the renewal,utilization,transformation and regeneration of the landscape space of industrial sites.

Study on the hybrid energy storage for industrial park energy systems:Advantages,current status,and challenges

In order to increase the renewable energy penetration for building and industrial energy use in industrial parks,the energy supply system requires transforming from a centralized energy supply mode to a distributed+centralized energy supply mode.The application of a hybrid energy storage system can effectively solve the problem of low renewable energy utilization levels caused by a spatiotemporal mismatch between the energy source and load.This study summarized the advantages and limitations of common energy storage technologies in industrial parks from the aspects of service life,response time,cycle efficiency and energy storage density,etc.The advantages of the hybrid energy storage system in industrial parks were also discussed in terms of sustainable development,climate change mitigation,social impact,and other aspects.The typical frameworks of hybrid energy storage were summarized,and the advantages,disadvantages,and application scenarios of each typical framework were analyzed.The current status of hybrid energy storage systems was summarized from the aspects of system modeling,hybrid energy storage mechanisms,design optimization,and operation dispatching.At the same time,the key challenges in modeling,regulation,and optimization of hybrid energy storage systems were discussed.This discussion leads to proposals for the direction of future research.The optimization methods and processes for designing and operating hybrid energy storage systems were proposed based on theoretical frameworks and methods.It is hoped that this review can provide some guidance and serve as a reference for developing and applying hybrid energy storage systems in industrial parks.
