Hybrid and intermittent characteristics of the distributed energy resources (DERs) bring great challenges to the security control and economic dispatch (ED) of the microgrids. To bypass these hurdles, this article proposes a multiagent system-based integrated design of security control and ED to guarantee the effective and economical operation of the interconnected microgrids. First, a hierarchical control scheme is constructed by two-level unit agents, in which the switching control and dynamic regulation are fully implemented with the corresponding hybrid behaviors based on the differential hybrid Petri-net (DHPN) model. Based on the DHPN model, a novel dynamic ED integrated with security control is proposed to overcome the issues that cannot be solved in conventional models. Furthermore, to reduce the computational complexity and unified the mathematical model of the DERs, the inverter-based power control strategy is converted to a predictive control model which can be decomposed into several subsystems. In the optimization process, all the subsystems are implemented in a fully distributed, communication free, and rolling optimization manner based on the distributed model predictive control (DMPC). The validity of the proposed design is demonstrated according to the simulation results in case studies.

基于多主体系统的互联微电网系统安全控制与经济调度集成设计

分布式能源（DER）的混合和间歇特性给微电网的安全控制和经济调度（ED）带来了巨大挑战。为了克服这些障碍，本文提出了一种基于多代理系统的安全控制和ED集成设计，以确保互连的微电网的有效和经济运行。首先，由两级单元代理构建分级控制方案，其中基于差分混合Petri网（DHPN）模型，以相应的混合行为完全实现了切换控制和动态调节。基于DHPN模型，提出了一种新型的具有安全控制功能的动态ED，以克服传统模型无法解决的问题。此外，为了降低计算复杂度并统一DER的数学模型，将基于逆变器的功率控制策略转换为可分解为多个子系统的预测控制模型。在优化过程中，所有子系统都基于分布式模型预测控制（DMPC）以完全分布式，无通信和滚动优化的方式实现。根据案例研究中的仿真结果证明了所提出设计的有效性。分布式模型预测控制（DMPC）的滚动优化方法。根据案例研究中的仿真结果证明了所提出设计的有效性。分布式模型预测控制（DMPC）的滚动优化方法。根据案例研究中的仿真结果证明了所提出设计的有效性。
