Microgrid Optimization Scheduling Model
A multi-strategy Improved Multi-Objective Particle Swarm Algorithm (IMOPSO) method for microgrid operation optimization is proposed for the coordinated optimization problem of microgrid economy and environmental protection. A grid-connected microgrid model containing. . Under the dual pressures of energy shortages and environmental challenges, the microgrid, as a distributed energy system integrating multiple energy resources, has become one of the key technologies for the efficient use of new energy and intelligent dispatching. With the aim of reducing operating costs and carbon emissions. . To optimize the objective function, an Improved Dung Beetle Optimization algorithm (IDBO) is proposed. Whenever the algorithm experiences a new state–action pair, this experience is recorded as part of the training data.

Microgrid protection technology protection strategy
This paper presents a comprehensive review of the available microgrid protection schemes which are based on traditional protection principles and emerging techniques such as machine learning, data-mining, wavelet transform, etc. . If microgrids are to become ubiquitous, it will require advanced methods of control and protection ranging from low-level inverter controls that can respond to faults to high-level multi-microgrid coordination to operate and protect the system. The design of both systems must consider the system topology, what generation and/or storage resources can be connected, and microgrid operational states (including grid-connected, islanded, and transitions between the two). This paper presents a resilient hybrid protection framework. . The main protection challenges in the microgrid are the bi-directional power flow, protection blinding, sympathetic tripping, change in short-circuit level due to different modes of operation, and limited fault current contribution by converter-interfaced sources. In particular, they can impact conventional protection practices in distribution. .
