The proposed system is intended to decrease the initial cost of the system. A master-slave control system is employed to distribute power among parallel systems. The storage inverter serves as the master inverter and is responsible for maintaining the system output voltage within an acceptable range.
This study proposes a master-slave control system for controlling parallel inverters connected to a PV system. The master inverter is connected to Energy Storage Devices (ESDs) and is responsible for maintaining stable voltage on the load bus.
In the master–slave control structure, a distributed generation or energy storage device is set as the master power supply, which adopts the V/f control to provide the stable voltage and frequency for the microgrid, and coordinate other slave power supplies adopting PQ control to achieve the power balance of the microgrid.
The V/f control adopted by the master power supply has problems of slow dynamic response, poor anti-interference ability in response to micro-source output power fluctuations and loads abrupt change. Aiming at problems of the output voltage mentioned above, an improved V/f control strategy based on compound control is proposed in this study.
The master inverter connected to ESDs maintains constant system voltage and compensates for any deficit in PV-generated power. The performance of a system comprising two PV units and one ESD unit connected to three parallel inverters was evaluated using a simulator, through four case studies of different load and radiation change patterns.
A plug and play device for customer-side energy storage and an internet-based energy storage cloud platform are developed herein to build a new intelligent power consumption mode with a flexible interaction suitable for ordinary customers.
