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...
In this paper, the system stability-constrianted optimal protection coordination (SSCOPC) as stochastic problem in the microgrid with grid-connected and islanded operation modes, including renewable energy sources (RESs) and energy storage systems (ESSs), is presented. This problem to optimal regulation of the dual setting overcurrent relays (DSORs) and selecting the reactance size of fault cur...
Disconnecting microgrid from main grid, may lead to severe frequency changes. Under frequency load shedding method provides a proper protection scheme by shedding certain amount of loads. Under frequency load shedding relay is used for frequency control of islanded microgrid. Each synchronous distributed generator (DG) of microgrid is equipped with a protective islanding detection device such a...
Increasing the number of microgrids has raised the complexity and nonlinearity of the power system and conventional controllers do not present acceptable efficiency in a wide range of operation points. In this study, a fractional order proportional–integral–derivative controller optimized with hybrid grey wolf-pattern search algorithm is used to control the frequency of each area of the microgr...
In recent years, DC microgrid has attracted considerable attention of the research community because of the wide usage of DC power-based appliances. However, the acceptance of DC microgrid by power utilities is still limited due to the issues associated with the development of a reliable protection scheme. The high magnitude of DC fault current, its rapid rate of rising and absence of zero cros...
This work includes a high step up voltage gain DC-DC converter for DC microgrid applications. The DC microgrid can be utilized for rural electrification, UPS support, Electronic lighting systems and Electrical vehicles. The whole system consists of a Photovoltaic panel (PV), High step up DC-DC converter with Maximum Power Point Tracking (MPPT) and DC microgrid. The entire system is optimized wi...
