摘要

针对基于能量路由器（ER）间接接纳分布式光伏的高渗透率光伏配电网由于本地台区光伏消纳或出力不足导致的弃光及功率缺额问题

引入高渗透率光伏能量路由器互联系统（HP-PVERIS）

提出一种基于泛化图论和深度确定性策略梯度（DDPG）算法的双层相干驱动能量路由策略。第一层通过定义多目标优化模型

针对节点转换损耗、线路损耗、网络拥塞及能量负载均衡问题

利用改进的泛化图论求解路由路径;第二层基于DDPG强化学习算法对多路径进行最小损耗目标的动态功率分配

并将优化后的新拓扑参数反馈至第一层

形成双层驱动的路由分配策略。仿真结果表明

该策略能够有效改善网损、网络拥塞及负载均衡问题

同时提升高渗透率光伏配电网的光伏消纳和互济能力。

Abstract

To address PV curtailment and power deficits in high-penetration PV distribution networks using energy router （ER）

this paper introduces a high-penetration photovoltaic energy router interconnection system （HP-PVERIS） and proposes a two-layer coherence-driven energy routing strategy combining generalized graph theory and deep deterministic policy gradient （DDPG）. The first layer uses an improved generalized graph theory model for multi-objective optimization of node conversion loss

line loss

congestion

and load balancing. The second layer applies DDPG-based dynamic multi-path power allocation

feeding optimized topology parameters back to the first layer to form a bi-layer routing strategy. Simulations show the approach effectively reduces losses

alleviates congestion

balances loads

and enhances PV accommodation and interconnection capacity.
