摘要

动态可重构电池可通过内部电力电子网络进行灵活拓扑重组，实现本质安全运行，但由于每个储能单元内部电池网络实时独立重构，导致其对应的大规模储能电站海量储能单元间运行状态各异，约束边界不一，显著增加了电站运维成本。为此，通过充分考虑大规模动态可重构电池储能电站海量储能单元运行状态与多维动态边界约束，提出一种功率优化的动态调控方法。该方法充分考虑储能单元每次动态重构后的约束边界，建立包含动态可重构电池损耗成本、温度调节成本、运行维护成本和荷电状态均衡性等关键因素的系统运维优化模型，并采用多元定权法确定各因素的优化权重。通过算例仿真，验证了该方法能够在保证动态可重构电池储能电站海量储能单元独立运行约束下显著提升电站运维经济性，同时改善储能单元状态参数的一致性。

Abstract

Dynamically reconfigurable batteries can achieve intrinsically safe operation through flexible topological reconfiguration by an internal power electronics network. However

the real-time and independent reconfiguration of the battery network inside each energy storage unit leads to disparate operating states and inconsistent constraint boundaries among the massive energy storage units in the corresponding large-scale energy storage power stations

which significantly increases the operation and maintenance costs of the power stations. To address this issue

this paper proposes a dynamic power optimization control method that fully accounts for the operating states and multidimensional dynamic boundary constraints of the massive energy storage units in large-scale dynamically reconfigurable battery energy storage stations. The method fully takes into account the constraint boundaries of energy storage units after each dynamic reconfiguration

and establishes a system operation and maintenance optimization model incorporating key factors such as the degradation cost

temperature regulation cost

operation and maintenance cost of dynamically reconfigurable batteries

and the state of charge balance. In addition

a multi-variate fixed weight method is applied to determine the optimization weights of each factor. Finally

case study simulations demonstrate that the proposed method can significantly improve the operation and maintenance economy of the power station while ensuring the independent operation constraints of the massive energy storage units in the dynamically reconfigurable battery energy storage power station

and simultaneously enhance the consistency of their state parameters.
