摘要(Abstract):
大规模新能源并网对电力系统调节能力提出更高的要求,为充分发挥分轴燃气-蒸汽联合循环机组的调节作用,亟需探索并建立安全、可靠、稳定的现货市场参与机制。首先分析对比了国内外分轴燃机参与市场不同机制的特点及适用性,结合浙江电力市场建设经验,详细介绍了基于独立建模的分轴燃机参与现货市场机制:将分轴燃机按单机形式独立建模,燃机出力决定汽机出力,解决了机组建模方式中的依赖关系;将燃机报价纳入目标函数,燃机和汽机出力比例纳入约束条件,解决了套机运行方式多变的问题。之后,通过对浙江现货市场运行实测数据进行分析,验证模型设计、控制和收益指标结果的合理性。最后总结经验并为现货市场的多样性发电主体参与机制设计提供支撑。
Large-scale integration of new energy presents higher demands on power system regulation capacity. In order to give full play to the regulation function of split shaft gas-steam combined cycle units,it is urgent to explore and establish a safe,reliable,and stable power spot market participation mechanism. Firstly,the characteristics and applicability of different market mechanisms for split-shaft gas turbines at home and abroad are compared and analyzed. Secondly,a mechanism based on independent modeling for split-shaft gas turbines participating in power spot market according to the experience of power market construction in Zhejiang province is introduced in detail.The split-shaft gas turbines are modeled separately,and steam turbine output is determined by the gas turbine output,which puts an end to the dependence relationship between the gas turbines and steam turbines. The gas turbine bid is incorporated into the objective function,and the ratio of gas turbine and steam turbine output is incorporated into the constraint conditions,which solves the problem of the variable operation mode of split-shaft gas turbines.Then the measured data of Zhejiang spot market is analyzed to verify the rationality of the model design,control,and income index results. Finally,experience is summarized and provided for diversified generation entities to participate in mechanism design in the spot market.
