特高压交直流建设时序优化评估指标体系

Timing Optimization Evaluation Index System of UHVAC and UHVDC Project Construction

为全面衡量整个建设期内特高压交直流工程不同时序方案的合理性并比较优劣性,建立包含经济、技术、安全稳定及社会环境等因素的评估指标体系。结合特高压交直流电网发展的特点,提出采用输电阻塞费用、结构均衡度、社会环境影响等指标,与静态安全性等常规输电网规划评估指标共同组成综合评估指标体系,用以反映不同时序方案对清洁能源接入的适应性、网络结构的均衡性和节能减排效果等。

To comprehensively evaluate the rationality and advantage of UHV AC-DC project timing programs during the whole construction period,this paper establishes the evaluation index system including economy,technology,security and stability,social environment and other factors. Considering the development characteristics of UHV AC-DC power grid,we suggest using transmission congestion fees,structure balancing,social environmental influence and other some conventional transmission network planning evaluation indexes such as steady-state security,to compose the comprehensive evaluation index system,in order to compare and analyze clean energy development adaptability,power grid structure balancing,the effect of energy-saving and emission reduction,etc. in different UHVAC and UHVDC project construction timing programs.
