摘　　要：综合能源系统的多能互补特性有助于间歇性可再生能源的消纳。为了体现综合能源系统的市场价值并鼓励其投资和发展,综合能源供应商参与多能源市场竞争将是一种趋势。该文研究拥有风电机组的综合能源供应商同时参与电力批发市场与天然气市场的竞争问题,考虑电转气设备和燃气轮机等电气转换装置,并在天然气价格普遍比电力价格低的背景下引入实时天然气市场弥补综合能源供应商投标偏差,建立一个包含风电及电气转换装置的综合能源供应商参与投标竞争的多能源市场联合均衡模型,并采用非线性互补方法求解该均衡模型。算例分析验证了模型的合理性和有效性,并表明综合能源供应商增加风电比例有助于降低日前电价、实时气价和日前气价,并会增加综合能源供应商的利润和社会福利。The multi-energy complementary nature of integrated energy systems facilitates the absorption of the intermittent renewable energy sources.In order to reflect the market value of integrated energy systems and encourage their investment and development,it will be a trend for the integrated energy providers to participate in the multi-energy market competition.This paper studies the problem how the integrated energy suppliers with wind power generators participate in the competition of the electricity wholesale market and the natural gas market at the same time.We consider the electric conversion devices such as the power to gas equipment and the natural gas generating units,and introduce the real-time natural gas market to make up for the bid deviation of the integrated energy suppliers under the background that the natural gas price is generally lower than the electricity price.A multi-energy market joint equilibrium model with the strategic biddings between the integrated energy suppliers including wind power and the electric conversion equipment is established,and the nonlinear complementary method is used to solve the equilibrium model.Numerical examples are presented to verify the reasonableness and effectiveness of the model,and the results show that the increase of the proportion of wind power will help to reduce the prices in the day-ahead electricity market,and the real-time and the day-ahead gas markets,promoting the profit and social welfare of each of the integrated energy suppliers.
