摘要:  摘要:随着电转气(power-to-gas,P2G)技术的不断发展和商业化应用,风电机组(wind power generation unit,WPGU)与电转气设备的协同运行逐步受到关注。电转气设备的运行方式比较灵活,可有效平衡风电出力波动,二者可协同形成虚拟电厂(virtual power plant,VPP)参与电力市场运营。在此背景下,研究了含风电机组与电转气设备的虚拟电厂竞价策略。首先构建了含风电机组与电转气设备的虚拟电厂参与电力市场运营的模型架构。之后,以最大化总体收益为目标,构建了虚拟电厂在日前电力市场的竞价策略模型,并确定虚拟电厂自调度运行策略。然后,考虑到风电出力预测误差的不确定性,发展了基于信息间隙决策理论(information gap decision theory,IGDT)的鲁棒竞价策略和机会竞价策略,以反映虚拟电厂不同的风险偏好水平。接着,采用成熟的商用求解器AMPL/IPOPT求解所构造的非线性优化模型,确定针对预期成本的鲁棒和机会竞价策略。最后,以北欧电力市场的实际数据为例说明所构建的优化模型和采用的求解方法的基本特征。

Abstract:  ABSTRACT:  With the continuous development and commercialization of power-to-gas (P2G) technology, the coordinated operation between wind power generation units (WPGUs) and P2G facilities has attracted more and more attentions. The operational flexibility of P2G facilities can be employed to mitigate power output fluctuations of WPGUs, while both P2G facilities and WPGUs can form a virtual power plant (VPP) to participate in electricity market operation. Given this background, this paper studies the optimal bidding strategies for the VPP including WPGUs and P2G facilities. First, we present a modeling framework for a VPP with WPGUs and P2G facilities to participate in the operation of an electricity market. Then we construct the bidding strategy model for a VPP in a day-ahead electricity market with the objective of maximizing the overall profit, and determine the self-scheduling strategy of VPP. Considering uncertain forecasting error of the fluctuant outputs from wind power units, we develop both robust and opportunity bidding strategy models based on the information gap decision theory (IGDT), so as to reflect the risk preferences of various VPPs. And then, we adopt the well-developed commercial solver AMPL/IPOPT to solve the proposed nonlinear optimization model, and determine the robust and opportunity bidding strategy models for expected cost. Finally, case studies based on data from the Nord pool electricity market are carried out to demonstrate the characteristics of the developed optimization models and the employed solving method.
