摘要: 积极发挥农户自建生物质反应器、光电设备、光热设备的供能支撑作用,引导构筑面向个体用户、具备孤岛自主运行能力的低碳微型综合能源系统,对削减用户集中式供能路径赖具有裨益。针对农村绿能生产设备多样化、用能行为复杂化造成的碳排放路径模糊问题,提出一种内嵌主从分布物理知识的多层卷积神经网络(PI-CNN),通过主、从知识库间深度交互发掘用户用能行为与碳排放间的映射关系,实现碳排放路径的精准追踪。汲取PI-CNN网络学习结果,对碳排放路径、辐射状配电网潮流、用户热电分时价格分配适宜优化权重,设计计及运行综合碳排放、电网全局潮流均匀度、用户用能总收益的能量管理策略评估模型,量化用能方案质量。考虑到集中式不均匀多目标优化问题求解困难,结合自适应梯度算法(AdaGrad)求解数学问题,拟定兼顾经济性、低碳性、鲁棒性的综合能量管理策略。以华南某村落为例开展仿真分析,验证提出PI-CNN可行性和能量管理策略优越性。

Abstract: Actively leveraging the energy support role of self built biomass reactors, photovoltaic equipment, and photothermal equipment by farmers, guiding the construction of low-carbon micro comprehensive energy systems that are oriented towards individual users and have the ability to operate independently in isolated islands, is beneficial for reducing the reliance on centralized energy supply paths for users. A multi-layer convolutional neural network (PI-CNN) embedded with master-slave distributed physical knowledge is proposed to address the problem of carbon emission path ambiguity caused by the diversification of rural green energy production equipment and the complexity of energy consumption behavior. Through deep interaction between the master and slave knowledge bases, the mapping relationship between user energy consumption behavior and carbon emissions is explored, achieving accurate tracking of carbon emission paths. Drawing on the learning results of the PI-CNN network, optimize the weights of carbon emission paths, radial distribution network power flow, and user heat and electricity time of use price allocation, design an energy management strategy evaluation model that takes into account comprehensive carbon emissions, global power flow uniformity of the power grid, and total user energy consumption revenue, and quantify the quality of energy consumption schemes. Considering the difficulty of solving centralized non-uniform multi-objective optimization problems, a comprehensive energy management strategy that considers economy, low-carbon, and robustness is proposed by combining the adaptive gradient algorithm (AdaGrad) to solve mathematical problems. Taking a village in southern China as an example, conduct simulation analysis to verify the feasibility and superiority of the proposed PI-CNN energy management strategy.
