摘要：

针对可再生能源大规模接入电网背景下引发的能源供需失衡、运营效率低下等问题，提出了一种考虑园区多能耦合特性的虚拟电厂（VPP）运行优化模型。基于提出的面向多能耦合园区虚拟电厂的基础概念，建立了考虑多能耦合特性的虚拟电厂各类能源系统的功率平衡模型，可兼顾园区多能源经济运行与新能源消纳的需求；基于功率平衡模型建立多能耦合虚拟电厂的优化运行模型，并采用混合整数线性规划进行求解；基于引入了多能耦合设备的VPP进行仿真分析，验证了上述模型在提高园区异质能源综合利用率、降低运营成本、提升率等方面具有显著优势。

Abstract:

An optimized operation model for virtual power plants（VPPs），which considers the multi-energy coupling characteristics of energy parks，is proposed to address issues like energy supply-demand imbalance and operational inefficiency caused by large-scale integration of renewable energy into the power grid. First，the basic concept of a VPP tailored for a multi-energy coupling park was introduced. Then，a power balance model for various energy systems within the VPP was developed，taking into account both multi-energy economic operations and renewable energy consumption needs within the park. Building upon this power balance model，an optimal operation model for a multi-energy coupled VPP was formulated，utilizing mixed integer linear programming for solving the model. Finally，simulations were conducted on the VPP incorporating multi-energy coupling equipment，demonstrating that this optimized model significantly enhanced the comprehensive utilization efficiency of heterogeneous energy sources，reduced operational costs，and improved the rate of renewable energy consumption.

Key words: virtual power plant（VPP）, multi-energy coupling, optimized operation, local consumption, "dual carbon" target, total operating cost, renewable energy consumption
