摘要

随着能源结构的调整

可再生能源在原本冷热电气负荷主导的综合能源系统中的占比逐步提升

风光出力的不确定性与多能微网的频率稳定性面临挑战。考虑温度传播的热惯性

构建了风光出力接入冷热电气微网的调度模型。该模型在目标函数中综合考虑频率偏差的惩罚成本和系统的运行经济成本

通过混合整数线性优化理论求解系统的优化运行模式。算例仿真结果表明:在考虑了风光出力与冷热电气负荷产生的频率偏差特性后

系统运行成本中的频率惩罚部分降低了近95%

从而使系统具备更好的经济性和稳定性。

Abstract

With the adjustment of energy structure

the share of renewable energy in integrated energy systems dominated by cold

heat

electricity and gas loads has been steadily increasing gradually. The inherent uncertainties in wind and solar power generation and the frequency stability challenges faced by multi-energy microgrids has become prominent issues. Considering the thermal inertia of temperature propagation

a coordinated scheduling model with wind and solar power integrated into cold

heat

electricity and gas microgrids was constructed. The objective function comprehensively considered both frequency deviation penalties and operational economic costs

with system optimization achieved through mixed integer linear programming (MILP). Simulation results show that the frequency penalty components in operational costs reduce by approximately 95% with consideration of frequency deviations caused by wind and solar power generation and cold

heat

electricity and gas loads

thereby making both system economy and stability better.
