摘要:

随着互联电网的发展,跨区输电交易日益增加,区外电力送大区电网面临着电能消纳优化配置问题。基于此,提出了就地消纳、按各省火电装机容量比消纳、按各省负荷比消纳、按各省负荷与各省负荷中心到特高压落点的电气距离比消纳等4种消纳方式,定义了计及电价、碳排放的综合经济性指标,并利用火电替代率和火电出力率对消纳方式进行量化评估。选取华中电网作为大区电网,以特高压天中直流送华中电网为例进行分析,针对不同输电容量、丰枯条件和负荷空间给出相应的省间消纳方式,为区域电网调度运行部门提供依据和行之有效的定量决策手段。

Abstract:

With the development of interconnected grids and the increase of trans-regional transmission trading, the power outside sending to large area is faced with the problem of electric energy consumption optimization configuration. Based on this, we propose four electric power consumption modes of the power outside sending to large area by UHV DC: placement consumption, consumption according to the thermal power installed capacity ratio of each province, consumption according to the load ratio of each province, and consumption according to the ratio of the load to the electrical distance between load centers and placement of UHV in each province. Then, we define the comprehensive economic index with considering electricity price and carbon emission, and use thermal power replacement rate and thermal power output rate for the quantitative assessment of the consumption modes. An example of the power outside sending to central China power grid as large area by the Hami-Zhengzhou UHV DC is taken to be analyzed. Finally, we propose the corresponding consumption mode among the respective provinces based on different transmission capacity, wet and dry conditions and load space, which can provide an effective basis and a quantitative means of decision-making for regional power grid dispatching sector.

Key words: trans-regional transmission, large power grid, electric power consumption, comprehensive economic index, thermal power replacement rate, thermal power output rate
