摘要

可再生能源的拥塞和利用效率低下等问题阻碍了智能电网内能源共享的优化。本文通过在以产消为中心的SG系统中实现基于拥塞的定价模型来解决这些挑战。首先，制定了一个动态定价模型来解决线路拥堵问题，考虑了SG内光伏（PV）产消者的供需动态。此外，该模型结合了需求响应（DR）和交易能源（TE）机制，考虑到客户调整负荷的灵活性，并根据经济考虑和用户参与意愿设计成本模型。通过将发现的价格与客户供需联系起来，该方法旨在优化ES，同时确保基于Shapley价值的公平性，最终降低生产消费者成本并提高SG内的ES。此外，还进行了灵敏度分析，以验证所提出方法的有效性。所有的仿真和数值实验都是在Intel酷睿i7处理器和16gb RAM的系统上使用MATLAB R2023a进行的。

A novel congestion based pricing model for prosumer-centric smart grid systems

The optimization of energy sharing (ES) within smart grid (SG) systems is hindered by issues such as congestion and inefficient utilization of renewable energy sources. This article addresses these challenges by implementing a congestion-based pricing model in a prosumer-centric SG system. Initially, a dynamic pricing model is formulated to address line congestion, factoring in the supply and demand dynamics of photovoltaic (PV) prosumers within the SG. Additionally, the model incorporates demand response (DR) and transactive energy (TE) mechanisms, considering customers’ flexibility to adjust their loads, and designs cost models based on economic considerations and user willingness to engage. By linking the discovered price with customer supply and demand, this approach aims to optimize ES while ensuring Shapley value-based fairness, ultimately reducing prosumer costs and enhancing ES within the SG. Furthermore, a sensitivity analysis is conducted to demonstrate the effectiveness of the proposed method. All simulations and numerical experiments were performed in MATLAB R2023a on a system with an Intel Core i7 processor and 16 GB RAM.
