Distributed Control of Inverter-Based Power Grids

This paper investigates the operation of a currentcontrolled Voltage Source Converter (VSC) under weakgrid conditions caused by large grid impedance. Threedifferent current controller structures are investigated; theconventional decoupled PI-controller in the synchronouslyrotating reference frame, Proportional Resonant (PR)controllers in the stationary reference frame, a...

DC bus capacitors of Medium Voltage Cascaded STATCOM are independent. DC side voltage balance control method is the key influencing factor of current control. The imbalance of DC bus voltage increases harmonic current and affects the safety of device. In this paper, the unbalance mechanism of DC side capacitor voltage is analyzed. Based on the unipolar dual frequency and carrier phase-shifted S...

in the deregulated power systems, transmission congestion is one of the significant and main problems of the electrical networks which can cause incremental cost in the energy. this problem has resulted to new challenging issues in different parts of power systems which there was not in the traditional systems or at least had very little importance. transmission congestion happens when the maxi...

The proposed work is to analyze the power consumption of Finite Impulse Response (FIR) filter under different combinatorial modules. Under the considered modules namely Parallel, serial and Distributed Arithmetic(DA) architectures, effects of variation of clock frequency, leakage capacitance, supply voltage are chosen to determine power consumption and junction temperature. Each module is simul...

This letter proposes a decentralized control scheme for grid-connected cascaded modular inverters without any communication, and each module makes decisions based on its own local information. In contrast, the conventional methods are usually centralized control and depend on a real-time communication. Thus, the proposed scheme has advantages of improved reliability and decreased costs. The ove...

A distributed graph processing system that provides locality control, indexing, graph query, and parallel processing capabilities is presented. Keywords—graph, distributed, semantic, query, analytics

Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...
