摘要
针对风电机组调频特性弱且单一储能装置无法满足全时间尺度功率能量需求的问题,提出了风储制氢电厂的一次调频控制策略.首先,依据传统同步机组一次调频功率输出特性,确定风储制氢电厂一次调频所需功率支撑.其次,通过分析电制氢装置(P2H)作为一种大容量可控负荷参与系统调频的可行性,对比不同储能介质的应用特点,选取超级电容与电制氢装置减载的多能协同调频方法.进而,针对分布式储能集中制氢架构的风储制氢电厂的特点,提出了一种多能协同的一次调频控制策略.最后,通过建立给予不同风速初始状态的风储制氢电厂仿真模型,验证了所提控制策略的有效性与合理性.
Abstract
In order to solve the problem that the frequency regulation characteristics of wind turbines are weak and a single energy storage device can't meet the power and energy demand of the full time scale,the primary frequency regulation control strategy of SCESS-DFIG-P2H generating station is proposed.Firstly,according to the primary frequency regulation power output characteristics of the traditional synchronous unit,the power support required for the primary frequency regulation of the SCESS-DFIG-P2H generating station was determined.Secondly,by analyzing the feasibility of electric hydrogen production unit(P2H)as a large capacity controllable load to participate in system frequency regulation,and comparing the application characteristics of different energy storage media,the multi-energy collaborative frequency regulation method of SCESS and P2H load reduction is selected.Furthermore,a multi-energy cooperative primary frequency regulation control strategy is proposed according to the characteristics of SCESS-DFIG-P2H generating station with distributed super capacitor energy storage and centralized hydrogen production architecture.Finally,the effectiveness and rationality of the proposed control strategy are verified by establishing the simulation model of the wind-storage-hydrogen station with different initial wind speed states.
