请翻译由于新能源发电的随机性、间歇性和波动性给电力系统带来冲击为保障新能源并网消纳以及系统的可靠性、安全性会不断增加配套的辅助性服务设施导致系统成本不断上升。有研究发现当可再生能源渗透率在38-39时每日系统总成本为008亿元 -009亿元17；当可再生能源渗透率在40-75时每日系统全周期成本为107亿元-164亿元18；

Due to the randomness, intermittency, and volatility of renewable energy generation, it has brought impact to the power system. In order to ensure the integration and consumption of renewable energy and the reliability and safety of the system, there will be a continuous increase in supporting auxiliary service facilities, leading to a continuous increase in system costs. Studies have found that when the penetration rate of renewable energy is between 38% and 39%, the daily total cost of the system is 0.08 billion to 0.09 billion yuan; when the penetration rate of renewable energy is between 40% and 75%, the daily full cycle cost of the system is 1.07 billion to 1.64 billion yuan
