The paper introduced the power converter system's control strategy under the photovoltaic(PV)/battery micro-grid system's different operating modes firstly. Under the grid-connected operating mode, the voltage of micro-grid point of common coupling(PCC) may be affected by the variation in load an...
New regulations have been introduced by TSOs and DSOs at the connection point between the main power grid and RESs, which can be referred to as the point of common coupling (PCC) (Battaglini et al., 2009). It requires RESs to act similar to traditional power plants and play an important...
The control architecture of the presented system incorporates a synchronous reference frame phase-locked-loop (s-PLL), a stationary frame current controller, a dc-link voltage controller, a dc-dc boost converter controller and a maximum power point tracking (MPPT) algorithm. Control design ...
then designed linear optimal controller for the system.The inverter integrates three functions including maximum power point tracking(MPPT),step-up/down DC-side voltage and output grid-connected.The simulation and experiment are performed to validate the strategies: when input condition of the ...
Summary It is well known that linear controllers are designed by using small-signal approximation around a certain operating point that cannot guarantee th... A Zakipour,S Shokri‐Kojori,MT Bina - 《International Transactions on Electrical Energy Systems》 被引量: 4发表: 2017年 Current PIλ Con...
PV array and wind turbine are individually controlled to operate at the maximum power point for the most use of renewable energy. The BESS operates as an energy buffer to flexibly shift the generation from the renewable energy sources without excessively frequent shifts between battery charging and ...
This document presents an analytical stability method to maintain the grid stability by adjusting the generator control parameters based on the impedance frequency response measured at the point of connection.关键词: distributed power generation distribution networks frequency response photovoltaic power ...
The DFCs can eliminate the shading effect by using the individual maximum power point tracking. In conventional flyback-type single-phase utility-interactive inverters, discontinuous conduction mode and boundary conduction mode are popular because of the inherent constant current-source characteristics more...
