Multi-objective planning and optimization of microgrid lithium iron phosphate battery energy storage system consider power supply status and CCER transactions

Lithium iron phosphate battery (LIPB) is the key equipment of battery energy storage system (BESS), which plays a major role in promoting the economic and stable operation of microgrid. Based on the advancement of LIPB technology and efficient consumption of renewable energy, two power supply planning strategies and the china certified emission reduction (CCER) model are proposed respectively. Based on it, the multi-objective planning optimization model with economic benefits, environmental benefits and power supply stability as the objective function is established for the first time, and the Newton Weighted Sum Frisch method (NWSFA) solution model is adopted. In the planning process, rain flow counting method is used to research the life of BESS, which improves the accuracy of energy storage annual cost calculation. A park in northern China is taken as a case study to demonstrate the application of this model. The simulation results show that the annual economic operating cost of BESS is decreased by 18.81%, the energy supply reliability is increased by 0.15%, and the optimal electricity price adjustment ratio of the system is 15%.

An optimization decision support approach for risk analysis of carbon emission trading in electric power systems

Concerns over dramatic increasing electricity demand, exacerbating power shortage and changing climatic condition are emerging associated with municipal electric power systems (EPS). In this study, a risk-explicit mixed-integer full-infinite programming (RMFP) approach is developed for planning carbon emission trading (CET) in EPS. RMFP-CET has advantages in risk reflection and policy analysis, particularly when the input parameters are provided as crisp and functional intervals as well as probabilistic distributions. The developed method is applied to a real case study of CET planning of EPS in Beijing. Various electricity policies are incorporated within the modeling formulation for enhancing the RMFP-CET's capability. The results indicate that reasonable solutions have been generated, which are useful for making decisions of electricity production and supply as well as gaining insight into the tradeoffs among electricity supply risk, system cost, and CO₂ mitigation strategy.     

Framing processes in planning disputes: analysing dynamics of contention in a housing project in Hong Kong

Opposition to planned housing projects can lead to considerable delays. Hong Kong is characterized by an executive-dominant planning system, whereby the government possesses strong planning powers, while elected district councillors play an advisory role only. Curiously, planning delays are fairly common. The above paradox is analysed in this paper through examining a major dispute over public housing development in Hong Kong. This dispute involved lengthy processes of bargaining, which were vulnerable to legitimacy challenges. Councillors acted strategically by tapping into prevailing social values to frame the legitimacy of bargaining processes. Despite discontent with these informal bargaining processes, the dispute has not evolved into more radical challenges to existing governance arrangements. The paper concludes by considering how hegemonic discourses of planning efficiency may have constrained the emergence of radical contention, which adds to broader debates about the conditions which shape the trajectories and transformative prospects of contentious urban developments.     

产业集群视角下独立工矿区转型策略研究：以晋城“老三矿”为例

独立工矿区经历了重点发展、逐步式微至当前转型的历史时期,如何推动独立工矿区的存量更新成为促进城市可持续性的重要议题。城市作为区域经济政治和文化的聚集中心凝聚了大量的社会资源并辐射周边,地理空间分布的差异直接影响区域城市职能与发展潜力,因此本文以空间区位为划分依据,对独立工矿区进行了分类比较,分析其形成背景与发展特征,从产业集群的视角出发对三种不同类型独立工矿区转型提出了紧跟市场需求、贴合政策环境、整合内外资源和强调文化延续四个方面的规划策略,并以晋城古书院矿、王台铺矿和凤凰山矿为例剖析了城中型、近郊型和远郊型三类独立工矿区的转型实践,以期为独立工矿区的转型发展提供实施建议。
