Contact UsAbstract: For an AC-stacked photovoltaic (PV) inverter system with N cascaded inverters, existing control methods require at least N communication links to acquire the grid synchronization signal. In this paper, a novel decentralized control is proposed.
In this paper, a novel decentralized control is proposed. For N inverters, only one inverter nearest the point of common coupling (PCC) needs a communication link to acquire the grid voltage phase and all other N 1 inverters use only local measured information to achieved fully decentralized local control.
Conclusions This paper proposes a one-communication-link decentralized control for AC-stacked PV inverter system. It achieves the following objectives: It reduces the communication complexity to a great extent compared with existing control methods. Specifically, it reduces N 1 communication links for a system with N inverters.
Second, the integration of a photovoltaic generator (PVG) into the microgrid allows for examining the compatibility of VC-VSIs and CC-VSIs under the proposed decentralized control strategy. A DC/DC stage is therefore required to optimize the energy efficiency of the PVG by implementing a maximum power point tracking (MPPT) process.
In this way, distributed control methods or even fully decentralized control methods are much easier to implement, which means the communication complexity is much lower and the system's reliability is higher. In this way, the AC-stacked PV inverter system has great potential for large-scale MV/HV grid-connected distributed PV generation.
Renewable energy generation is drawing more and more attention in the past decades [1–5]. AC-stacked photovoltaic (PV) inverter architecture is now considered a promising PV generation configuration [6–12]. It facilitates the integration of low voltage (LV) PV generators into medium/high voltage (MV/HV) grid due to its AC-stacked characteristic.
