摘要:

针对能源系统弃风光率高、出力不稳定、经济效益低的问题,提出一种面向含高比例可再生能源园区混合储能系统的协调调度方法,以提升经济效益、降低碳排放为目标.该方法充分利用不同储能的动态响应特性与容量差异:氢储能主要承担大功率、小波动的调节需求,电化学储能主要承担小功率、大波动的调节需求,天然气储能在氢储能和电化学储能的基础上进一步增加储能系统的灵活性,平衡园区能源系统的总功率.该方法充分考虑风电、光伏出力、本地负荷与电价的不确定性,构建跨季节-单日-实时多时间尺度调度框架:在跨季节调度阶段,根据四季典型预测数据决策氢储能和天然气储能的全年存储状态;在单日调度阶段,根据单日长期预测制定混合储能的功率调度指令;在实时调度阶段,结合单日调度结果与不确定场景的短期预测,实时调整风电、光伏出力及联络线功率,制定最优运行方案.算例测试表明,所提方法有效降低了能源系统的弃风光率与碳排放,提升了经济效益.

Abstract:

To address the high curtailment of wind and solar power, unstable output, and low economic efficiency in energy systems, a coordinated dispatch method for hybrid energy storage system in renewable-rich parks is proposed, aiming to improve economic benefits and reduce carbon emissions. The proposed method fully leverages the dynamic response characteristics capacity differences of different energy storage type. The hydrogen storage system (HSS) primarily handles large-power, small-fluctuation regulation demands, while the battery storage system (BSS) is utilized for the low power demand with high power fluctuation, and gas storage system (GSS) improves system flexibility of the hybrid energy storage, and operates for the power balance of the energy system. The method takes into full account of uncertainties of wind turbines (WTs) output, photovoltaics (PVs) output, local power demand, and electricity prices. During the cross-season dispatch stage, the state of charges of HSS and GSS are determined based on the typical seasonal predicted data. In the single-day dispatch stage, power dispatch instructions for the hybrid energy storage system are generated according to long-term daily prediction. In the real-time dispatch stage, the WTs output is adjusted based on single-day dispatch results and short-term predictions of uncertainty scenarios to formulate an optimal operation plan. The numerical results show that the proposed method effectively reduces wind and solar curtailment and carbon emissions, while enhancing economic efficiency.

Key words: renewable-rich parks, hybrid energy storage system, cross-season energy-power dispatch, multi-timescale coordinated operation, stochastic optimization, carbon trading
