Load variation, distributed power output uncertainty and multi-microgrids network complexity have brought great difficulties to the frequency stability of whole microgrid. To address this problem, paper uses a multi-agent deep reinforcement learning(DRL) algorithm design controllers control multi-microgrids. Firstly, load (LFC) model for was built. Secondly, based on centralized training decent...

In this paper a new method is introduced to increase the resiliency of a distribution grid by forming robust microgrids after extreme contingencies following disasters. The method tries to serve as much load as possible by forming microgrids with alleviated vulnerability based on the Manchester model and optimal AC power flow. The main feature of the proposed method is that the formed microgrid...

decentralized control strategies are popular candidates in microgrids control because of their reliability and performance. conventionally, droop control (as a main decentralized strategy) is been utilized in order to prevent permanent droop of voltage and frequency after change in loads and also to share generated power between distributed generation units. in this paper, a new droop control s...

Integration of distributed generations (DGs) in power grids is expected to play an essential role in the infrastructure and market of electrical power systems. Microgrids are small energy systems, capable of balancing captive supply and requesting resources to retain stable service within a specific boundary. Microgrids can operate in grid-connected or islanding modes. Effective islanding detec...

Abstract Grid-connected microgrids comprising renewable energy, energy storage systems and local load, play a vital role in decreasing the consumption of fossil diesel greenhouse gas emissions. A distribution power network connecting several can promote more potent reliable operations to enhance security privacy system. However, operation control for multi-microgrid system is big challenge. To ...

Abstract: A stand-alone multi-microgrid (MMG) system can be formed by connecting multiple stand-alone microgrids (MGs). In the stand-alone MMG system where the frequencies of each MG system are different, a back-to-back (BTB) converter can be used for interconnecting the adjacent MG system. The frequency control performance of the MMG system can be improved by designing the suitable controller ...
