Given the increasing complexity and scale of power networks, the probability of system collapse has dramatically increased during natural disasters and malicious cyber attacks. The results of recent studies indicate the state-of-the-art solution to overcome these challenges is to partition existing power networks into several interconnected areas. To address this open problem, this paper presents a unified decision-making structure that consists of network partitioning and optimal operational planning issues. Unlike conventional partitioning mechanisms that overlook the physical characteristics of power grids, the proposed structure attempts to decompose the integrated power network into the optimal number of robust partitions by using the electrical modularity and electrical coupling strength (ECS) indicators. The partitioning mechanism is accomplished in line with an optimization problem to construct supply-sufficient partitions with the aim of increasing hosting capacity of renewable generation in partitioned areas and decreasing the exchanged power between available partitions. To this end, an operational planning problem is performed to determine the optimal allocation of wind farms (WFs), photovoltaic (PV) parks, and energy storage systems (ESSs) in each created partition. The proposed structure ensures the uniform distribution of renewable generation in the partitioned power networks. The presented partitioning and planning problem is applied to the IEEE 30-bus test system, and it is solved using GAMS software. The advantage of the proposed structure is demonstrated using a set of case studies. To assure precise performance assessment, optimization outputs are further analyzed by DIgSILENT PowerFactory for detailed monitoring of the effectiveness of the proposed structure under normal and emergency conditions.

分区电网中可再生能源和储能系统的最佳分配以创建供不应求的区域

鉴于电力网络的复杂性和规模日益增加，在自然灾害和恶意网络攻击期间，系统崩溃的可能性已大大增加。最近的研究结果表明，克服这些挑战的最新解决方案是将现有的电力网络划分为几个相互连接的区域。为了解决这个开放性问题，本文提出了一个统一的决策结构，其中包括网络分区和最佳运营计划问题。与忽略电网物理特性的传统分区机制不同，该提议的结构尝试通过使用电气模块性和电气耦合强度（ECS）指标将集成的电力网络分解为最佳数量的稳健分区。分区机制是根据优化问题来完成的，以构造供需充足的分区，目的是提高分区中可再生能源发电的承载能力，并减少可用分区之间的交换功率。为此，执行了一个操作计划问题，以确定在每个创建的分区中风电场（WF），光伏（PV）公园和能量存储系统（ESS）的最佳分配。所提出的结构确保了分区电网中可再生能源的均匀分布。提出的分区和计划问题已应用于IEEE 30总线测试系统，并使用GAMS软件解决了。通过一系列案例研究证明了所提出结构的优势。为了确保准确的绩效评估，
