摘要：

随着深度脱碳进程的不断推进,高比例新能源并网易引发的弃风与缺电并存现象亟待解决。为此,提出一种提升电力保供能力的配电市场点对点交易机制,以保障源荷不匹配期间的电力供应。首先,介绍了面向电力保供的配电日前市场交易机制,同时提出引导电力大用户参与电力保供的基本策略;其次,构建了配电市场中各参与主体的最大化利润模型;进而,利用自适应交替方向乘子法求解该模型得到市场出清结果和各参与主体的能量管理策略;最后,通过算例验证了所提模型的有效性及计算方法的正确性。仿真结果表明,风电不足时,通过政策引导电力大用户向居民用户售电可保证电力供应;该策略还可减少电力大用户购电成本4%,提高5%的运行效益。

Abstract:

As the deep decarbonization process continues to advance, the co-existence of wind abandonment and power shortage caused by a high proportion of new energy connected to the grid needs to be solved urgently. To this end, this paper proposes a peer-to-peer trading mechanism for distribution network users to enhance the ability of power preservation, in order to guarantee the power supply during the low valley of wind power output. Firstly, the distribution market peer-to-peer trading mechanism for power preservation is introduced, and the basic strategy of guiding large power users to participate in power preservation is proposed; secondly, the profit maximization model of each participating subject is constructed; then, the adaptive alternating direction multiplier method is used to solve the model to obtain the market clearing results and energy management strategies; finally, the effectiveness of the proposed model and the correctness of the computational algorithm are verified through the arithmetic example. Finally, the validity of the proposed model and the correctness of the computational algorithm are verified through examples. The simulation results show that the proposed method can guide the large power users to guarantee the power supply of residential users when there is a shortage of wind power, and the strategy can also reduce the power purchase cost of the large power users by 4% and improve the operational efficiency by 5%.

Key words: electricity market, electricity supply assurance, Nash equilibrium, adaptive alternating direction multiplier method, large power users
