Microgrid system architecture diagram HD version

What is the basic architecture of a grid system?

The basic architecture of a µGrid system is presented in Fig. 1 (a), which shows that a µGrid system generally consists of four parts: i) the distribution system, ii) the DG sources, iii) energy storage, iv) control and communications modules. Some of the details of each part of the system are discussed below. Fig. 1.

Which architecture and control methodology is best for microgrids?

According to Xiao et al. , there is not still a consensus as to which architecture and control methodology is the best for microgrids. It is worth noting that the microgrid is a complex system comprising of variety of subsystems which are non-linear and possess strong cross-coupling between them.

What are the different types of microgrid architectures?

AC, DC, and AC–DC hybrid microgrid are some of the architectures proposed in literature. With multiple renewable energy sources providing electrical energy simultaneously, the load sharing among different sources has to be controlled according to the individual capacities of sources.

What is a dynamic model of a dedicated microgrid structure?

Dynamic model of a dedicated individual microgrid structure is presented as follows: (2.11) d d t x ( t) = A x ( t) + B u ( t) y ( t) = C x ( t) + D u ( t) A dynamic model of all such dedicated microgrid units is obtained separately. Size of the overall system consisting a number of individual microgrids becomes significantly large.

What are the subsystems of a microgrid?

The microgrid architecture as SoS is depicted in Fig 3. As can be seen from this figure, the subsystems of the microgrid SoS are photovoltaic system, wind turbine and microturbine. There could be other distributed generation units, such as fuel cells and unconventional sources of generation among the subsystems.

How can a complete model of a microgrid system be obtained?

A comprehensive model of the entire microgrid system can be obtained by combining all DGs. As can be observed, all the DG units have PCU in common. Hence, the dynamic equations of each DG coupled with the equations of currents and voltages of the PCU will render the complete mathematical model of the DG system.
