Wind-solar-storage-hydrogen-water coordinated planning for zero-carbon island microgrid considering inertia and frequency modulation requirements
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.
