Residential microgrid has the capability to participate in the distribution grid as a very flexible and dynamic component for demand side energy management (energy efficiency, peak-load reduction, and demand response). Various hierarchical (appliance, home, and neighborhood level) advanced control algorithms need to be developed and validated for such residential microgrids. GridLAB-D is the mo...
Voltage source inverters (VSIs) are usually used for all kinds of distributed generation interfaces in a microgrid. It’s the microgrid’s superiority to power the local loads continuously when the utility fails. When in islanded mode the voltage and frequency of the microgrid are determined by the VSIs, therefore the power quality can be deteriorated under unbalanced and nonlinear loads. A volta...

The increasing energy demands are stressing the generation and transmission capabilities of the power system. Distributed generation (DG), which generally located in distribution systems, has the ability to meet some of the growing energy demands. However, unplanned application of individual distributed generators might cause other technical problems. The Microgrid concept has the potential to ...
Renewable Energy based microgrids are being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. The technical challenges associated with the operation and controls are immense. Electricity generation by Renewable Energy Sources is of stochastic nature such that there is a demand for regulation of voltage output in order to ...
A microgrid is composed of distributed power generation systems (DGs), distributed energy storage devices (DSs), and loads. To maintain a specific frequency in the islanded mode as an important requirement, the control of DGs' output and charge action of DSs are used in supply surplus conditions and load-shedding and discharge action of DSs are used in supply shortage conditions. Recently, mult...
One of the EU energy policy goals is development of utilization of renewable and small loacal power sources. Local balancing of power production and consumtion is aimed due to power transmission loses minimazation. In other words all energy consumed in separated small area (cottage, town, commune) should be produced within this area. Research it has been done so far shows that it is very hard, ...
In this paper a new methodology for determining the optimal level of automation in microgrids is proposed. In traditional distribution networks, automation is referred to the management of the fault in a more efficiently manner especially in medium voltage (MV) distribution network in order to improve the network reliability indices by reduction of average outage duration per consumer and meanw...
This paper describes the characteristics and optimal methods for the planning of stand-alone microgrid system, in order to improve the power supply reliability, increase the coefficient of utilization of renewable energy and reduce the cost of investment and operation. Next, the problems in the optimal planning for a stand-alone microgrid system are summarized, including the unique operational ...
Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...
