Microgrid is a part of the power distribution system which uses renewable energy based of power generation connected to the grid system. Multi energy power generation is composed of renewable energy systems including photovoltaic, wind turbine, energy storage and local loads. Testbed of a microgrid system is the technique to ensure stable operation during faults and various network disturbances...

The design of environment-friendly microgrids at the smart distribution level requires a stable behaviour for multiple state operations. This paper develops a Kalman filter based optimal feedback control method for the microgrid state estimation and stabilization. First, the microgrid is modelled by a discrete-time state space equation. Then the cost-effective smart sensors are deployed in orde...

Distributed energy storage (DES) plays an important role in microgrid operation and control, as it can potentially improve local reliability and resilience, reduce operation cost, and mitigate challenges caused by high penetration renewable generation. However, to ensure an acceptable economic and technical performance, DES must be optimally sized and placed. This paper reviews the existing DES...

Microgrids are expected to become part of the next electric power system evolution, not only in rural and remote areas but also in urban communities. Since microgrids are expected to coexist with traditional power grids (such as district heating does with traditional heating systems), their planning process must be addressed to economic feasibility, as a long-term stability guarantee. Planning ...

This project deals with the application of distribution generation with energy storage system connected to the low– voltage microgrid by coupling inverter for simultaneous energy management and other aucillary services that include the compensation of power quality disturbances. To address inaccurate power sharing problems in autonomous islanding microgrid, an enhanced droop control method thro...

A dynamic economic dispatch and control method is proposed to minimize the overall generating cost for a stand-alone microgrid in DongAo Island, which is integrated with wind turbine generator, solar PV, diesel generator, battery storage, the seawater desalination system and the conventional loads. A new dispatching strategy is presented based on the ranking of component generation costs and tw...

Hybrid microgrid consists of AC and DC grids, in which the interlinking converter is used to connect AC and DC microgrids. The droop control scheme is widely applied to hybrid microgrid control including interlinking converter because it can be used to control power in hybrid microgrid without communication. However, the existing steadystate error in conventional droop control might affect to t...
