This paper shows the behaviour of of a microgrid which is fed by a PV source and the output of the grid which is controlled by a hysteresis controller . Maximum Power Point Tracking (MPPT) is used to track the maximum power, a Boost (dc to dc) converter is used to obtain the impedance matching between the PV array and the load. A solar inverter is used to convert DC input current to AC current ...

In DC microgrids, constant power loads (CPLs) reduce the effective damping of DC-DC converter and may induce destabilizing effects into converter. To overcome such problems regarding CPL ensure large-signal stability converters in some feedforward terms are added to <tex-math notation="LaTe...

Microgrids are one of the most useful and efficient ways to integrate the renewable energy technologies in order to improve security, quality, reliability and availability of electricity supply. In order to achieve these benefits when a microgrid with a substantial amount of stochastic generation operates in grid connected mode but also during islanding mode, the use of storage systems is essen...

This paper presents a smart DC micro-grid system for plug-in electric vehicle charging and discharging. This DC microgrid integrates the plug-in battery electric vehicles (BEVs) & plug-in hybrid electric vehicles (HEVs) together with the AC supply module, storage energy module, and intelligent control module. By connecting with the AC power source and the storage energy module, this grid can of...

This paper presents a decentralized control method for distributed generations (DGs) in an islanded direct current (DC) microgrid. In most typical DC microgrids, a decentralized control method is based on a voltage droop control method. However, the grid voltage differs from node to node due to line voltage drop, and hence the power sharing ratio among DGs cannot be matched with as desired valu...

The microgrid (MG) concept is attracting considerable attention as a solution to energy deficiencies, especially in remote areas, but the intermittent nature of renewable sources and varying loads cause many control problems and thereby affect the quality of power within a microgrid operating in standalone mode. This might cause large frequency and voltage deviations in the system due to unpred...

Most of the distributed energy resources, loads and energy storage systems in a DC microgrid are equipped with power electronic converters. With the integration of advanced power electronics devices, a microgrid is able to utilize a broader range of technologies in its design and operation. A key feature of power electronic converter based systems is the ability to direct energy flow within a s...

Renewable energy is that can be used indefinitely. As a result, renewable sources such as solar photovoltaics developed. Conventional converters, typically to connect the microgrid battery, only change voltage. To link bidirectional converters are required. A converter available in variety of configurations. The control structure highly sophisticated obtain satisfactory output. This article pro...
