Scheduling Model of Carbon Capture Virtual Power Plant Considering Joint Operation

摘要: 为了增强电力系统的灵活性与经济性、促进新能源的消纳，针对碳捕集机组传统运行方式在新能源大规模并网背景下灵活性不足的问题。基于碳捕集设备的运行原理，考虑将区域内风电、光伏、储能与碳捕集电厂进行集成，通过虚拟电厂进行调度，使碳捕集设备采用火电、风电、光伏联合供电的方式运行。引入风光储碳捕集虚拟电厂联合运行系统总成本最小的目标函数，兼顾系统的环境友好性，建立考虑联合运行的碳捕集虚拟电厂调度模型，算例分析验证了本文所提模型能够显著促进风电、光伏的消纳并提高系统的经济性与环境友好性。

Abstract: In order to enhance the flexibility and economy of the power system and promote the consumption of new energy, the traditional operation mode of carbon capture units is not flexible enough under the background of large-scale grid connection of new energy. Based on the operation principle of carbon capture equipment, it is considered to integrate wind power, photovoltaic, energy storage, and carbon capture power plants in the region, and dispatch them through virtual power plants, so that the carbon capture equipment can operate in the mode of combined power supply of thermal power, wind power and photovoltaic. The objective function of minimizing the total cost of the com-bined operation system of the wind-solar carbon storage and capture virtual power plant is intro-duced, taking into account the environmental friendliness of the system, and a carbon capture vir-tual power plant scheduling model considering the combined operation is established. The example analysis verifies that the model proposed in this paper can significantly promote the absorption of wind power and photovoltaic, and improve the economy and environmental friendliness of the sys-tem.
