许多国家的电力系统正在经历根本性的变革，采用了大容量的可再生能源发电技术，如风力涡轮机和太阳能光伏。风能和太阳能的发电量是多变的，很难预测。因此，这类技术能力的不断增长预计将带来电力供需平衡方面的挑战。本文研究了蓄电池和燃气发电系统的作用，以适应大容量的风能和太阳能间歇发电，从而促进电力供需的匹配。采用燃气与电力网络(CGEN)模型对英国2030年冬、夏季典型周的燃气与电力网络运行进行了优化。量化了不同容量的蓄电池和燃气发电系统在降低风能削减和系统运行成本方面的作用，并与这些技术的年化成本进行了比较。
The power systems in many countries are undergoing a radical transformation through employing a large capacity of renewable generation technologies such as wind turbine and solar photovoltaic. The power generation by wind and solar resources are variable and difficult to predict. Therefore, growing capacities of such technologies is expected to introduce challenges regarding balancing electricity supply and demand. This paper investigates the role of battery storage and power-to-gas systems to accommodate large capacity of intermittent power generation from wind and solar and therefore facilitates matching electricity supply and demand. The Combined Gas and Electricity Networks (CGEN) model was used to optimize the operation of gas and electricity networks in GB for typical weeks in winter and summer in 2030. The role of different capacity of battery storage and power-to-gas systems in reducing the wind curtailment and operating cost of the system were quantified and compared with the annualized cost of these technologies.
