SUN PV PLANT CONTROL SYSTEM The INGECON® SUN Plant Controller helps the grid operator to manage the PV plant performance and to guarantee the quality and stability of the electricity supply. Maximum PV plant control An advanced algorithm combined with a fast and efficient communications system, with response times of less than one second, allows for a precise control of the active and reactive power delivered by the plant to the grid. The INGECON® SUN Plant Controller controls the PV inverters, ensuring compliance with the grid operator’s requirements at the Plant Controller PV plant connection point. It is also possible to manage energy storage systems and other devices such as diesel generators, through the use of INGECON® SUN STORAGE Power inverters. This is a flexible system that can easily be adapted to the needs and configurations of each particular plant, whilst complying with the country-specific standards and regulations. Continuous communication with all the devices The Power Plant Controller dynamically receives the grid operator’s setpoints. For this purpose, a number of communication protocols are incorporated such as Modbus TCP / RTU, DNP3, IEC 60870-5-101, IEC 60870-5104 and OPC UA. Likewise, it is also possible to add digital and analogue I/O modules in order to extend the communication capabilities with third-party devices. Furthermore, the INGECON® SUN Plant Controller permits communication with the plant SCADA to transmit the connection point data. It is also possible a manual control for temporary maintenance or engineering operations. www.ingeteam.com solar.energy@ingetea

Plant Controller Plant Controller Description of the complete system A PV plant with a plant controller typically consists of: INGECON® SUN Plant Controller, comprising two basic systems: metering and control. It can additionally incorporate a communication channel with the grid operator in order to receive the operating setpoints. INGECON® SUN PV inverters connected to the PV array. INGECON® SUN STORAGE battery inverters connected to the energy storage system. SCADA, plant monitoring system. Communications network. Connecting the INGECON® SUN Plant Controller with the different inverters,...

Plant Controller System Features Production Control Some of the active power control functions that can be implemented in the INGECON® SUN Plant Controller are: Active Power Curtailment. It controls the PV plant’s output power, limiting it to a desired value. Ramp Rate Control. It controls the power generated by the inverters, ensuring that the variation in the plant power output conforms to the established setpoint. So as to control control any power variation, it is necessary to add an energy storage system. Fast Frequency Regulation. The system adjusts the power production depending on...
