摘要:
      随着中国配售电业务的放开,电网公司承担起了保底增量配电网的角色。为帮助电网公司更好地保底接手增量配电网,对电网公司保底服务实施后的增量配电网投资策略进行了研究。分析了有效资产与输配电价的关系,将保底后的有效资产增长方式分为新建改造工程和提前、按时、延迟设备更替换优,以保底服务周期内累积收益值最大为优化目标建立了投资优化模型。在不考虑输配电价管控和考虑管控的约束下,对算例进行求解仿真和灵敏度分析。由此给出在更替时间允许下设备更替换优投资对有效资产的形成具有更直接的效益等一系列投资建议。
Abstract:
      With the opening of the electricity distribution business in China, the grid company takes the responsibility of taking over incremental distribution network. In order to help the state grid enterprises take over the incremental distribution network business, the investment strategy after default service of incremental distribution network is studied. By analyzing the relationship between the economic benefits and effective assets, the growth modes of effective asset after default service are divided into new reconstruction projects as well as early, on-time and delayed replacement/update of equipment. Then an investment optimization model is built to optimize the objective of maximizing the cumulative benefit during the default service period. The examples are calculated, simulated and analyzed in sensitivity with or without consideration of transmission and distribution price constraints. Finally, a series of investment strategy proposals are given, such as the investment in replacement/update of equipment has more direct benefits in the formation of effective assets if replacement time allows.
