摘要

光储联合电站同时参与电能量市场和调频辅助服务市场时，储能调节能力需在能量交易、偏差平抑和快速调频之间共享，易出现功率裕度重复占用、荷电状态（state of charge

SOC）能量裕度不足及多服务叠加工况寿命损伤低估。针对上述问题，提出一种计及电池电能量—调频耦合退化的光储联合电站多时间尺度协调竞价方法。日前阶段联合优化电能量申报、调频容量和SOC轨迹，将调频容量承诺转化为功率与持续响应能量裕度约束，并将电能量深循环、调频微循环及交互耦合损伤统一计入寿命成本；日内阶段采用模型预测控制（model predictive control

MPC）滚动修正储能出力，在中标曲线和容量承诺约束下协调偏差平抑、自动发电控制（automatic generation control

AGC）跟踪与SOC安全。基于5类典型场景和150个测试日的结果表明，完整方法未出现SOC越限和调频容量不可用；相较无MPC方法，偏差超限电量和偏差惩罚均降低约90.0%；相较无耦合退化方法，等效循环次数和寿命成本分别降低约9.4%和11.0%。在约18%预测误差的压力场景下，MPC仍保持SOC与调频容量安全，但超出剩余功率和能量裕度的偏差只能部分修正。结果说明，容量可交付约束、耦合退化内生化和日内闭环修正能够协同改善多市场参与的风险调整收益、运行可执行性和寿命友好性。

Abstract

When photovoltaic-storage hybrid plants participate simultaneously in energy and frequency regulation markets

storage flexibility must be shared among energy trading

imbalance mitigation and fast regulation

which may cause duplicated use of power reserves

insufficient state-of-charge (SOC) energy margins and underestimated degradation under stacked services. A multi-timescale coordinated bidding method considering energy–frequency regulation coupled battery degradation is therefore developed. In the day-ahead stage

energy bids

regulation capacity and the SOC trajectory are jointly optimized. Regulation commitments are converted into power-margin and sustained-response energy-margin constraints

while deep-cycle degradation

regulation-induced micro-cycle degradation and their interaction are internalized as lifetime cost. In the intraday stage

model predictive control (MPC) updates storage operation under cleared schedules and committed regulation capacity to coordinate imbalance mitigation

automatic generation control (AGC) tracking and SOC security. Tests using five typical scenarios and 150 operating days show no SOC violation or unavailable committed regulation capacity for the complete method. Compared with the method without MPC

excessive imbalance energy and imbalance penalty are both reduced by about 90.0%; compared with the method without coupled degradation

equivalent cycles and degradation cost are reduced by about 9.4% and 11.0%

respectively. Under a forecast-error stress scenario of about 18%

MPC still maintains SOC security and regulation availability

although deviations beyond the remaining power and energy margins can only be partially corrected. These results show that coordinated modeling of capacity deliverability

coupled degradation and intraday closed-loop correction improves risk-adjusted economic performance

operational feasibility and lifetime-preserving operation in multi-market participation.
