以可再生能源替代传统柴油机发电是实现海岛能源体系绿色低碳转型的有效途径,但高比例可再生能源接入微电网引发的低惯量问题极易导致系统频率失稳。为此,提出一种考虑海岛零碳微电网惯量及调频要求的风-光-储-氢-水协同规划方法,通过合理配置可再生能源机组与长短期储能及海水淡化系统容量为微电网提供足量惯量支撑,提高调频能力。根据海岛分布式电源和负荷的独有特性,分别分析风能、光能、长短期储能及海水淡化系统的惯量支撑能力,并计算微电网发生严重扰动后频率跌落的最低值;以一级负荷全年稳固运行为前提,以海岛微电网综合投资运行成本最小为目标,考虑微电网惯量及调频要求,搭建独立海岛容量规划模型;利用L-shape两阶段迭代优化方法处理模型中的随机规划问题。以福建某独立海岛微电网实际工程为例进行分析,结果表明,所提方法能够在零碳发电的前提下有效保障海岛微电网运行的安全性。
The replacement of traditional diesel-based power generation with renewable energy is an effective way to realize low-carbon transition of island energy system,however,the low inertia problem induced by the integration of high-penetration renewable energy into microgrid is prone to cause system frequency instabi-lity. Therefore,a wind-solar-storage-hydrogen-water coordinated planning method considering the inertia and frequency modulation requirements of zero-carbon island microgrid is proposed,which provides sufficient inertia support for microgrid and improves frequency modulation capability by rationally allocating the capa-cities of renewable energy units,long short-term energy storage,and desalination system. According to the unique features of distributed power generations and loads of island,the inertia support capacities of wind energy,solar energy,long short-term energy storage and desalination system are analyzed respectively,and the minimum value of frequency drop after occurring severe perturbation in microgrid is calculated. Under the premise of stable operation of the primary load in the whole year,a capacity planning model of independent island is proposed,which takes the minimum comprehensive investment operation cost of island microgrid as the object,and considers the inertia and frequency modulation requirements of microgird. The L-shape two-stage iteration optimization method is used to deal with the stochastic programming problem in the model. An actual project of independent island microgrid in Fujian is taken as the example for analysis,and results show that the proposed method can effectively guarantee the safe operation of island microgrid under the premise of zero-carbon power generation.
