摘要/Abstract

摘要： 高比例可再生能源接入给电力系统稳定性带来巨大挑战，同时知识经济时代对供电电能质量提出更高要求，电力系统调频问题逐渐凸显。火电机组是电力系统调峰调频的主力电源，其配置蓄热装置对系统调峰能力的影响已有较多的理论研究和实践验证。以300 MW机组为例，研究不同的蓄热装置配置方案对机组一次调频能力的影响。研究结果表明不同配置方案在不同时段对火电机组一次调频能力的影响不同。该研究对火电灵活性改造影响分析、电力系统一次调频缺口评估具有借鉴意义。

Abstract: High penetration of renewable energy has brought great challenges to the stability of power systems. Meanwhile, in the era of knowledge economy, higher requirements are put forward for power supply quality such that the issues of power system frequency regulation will gradually become prominent. Since the thermal power unit is the main power source for the peak-load regulation of power system, the thermal storage device equipped with the unit has been studied both theoretically and practically regarding its influence on the peak-load regulation capability of power system. This paper takes a 300 MW unit as the example to analyze the effect of different thermal storage device configurations on the unit's primary frequency regulation capacity. The results show that different configurations have different effects on the primary frequency regulation capacity of thermal power units at different time intervals. This study has positive reference significance for the analysis of the influence of thermal power flexibility transformation and the assessment of generation deficit of primary frequency regulation of power system.

Key words: thermal power, heat storage water tank, electric boiler with thermal storage, primary frequency regulation, 300 MW unit
