How does the control center communicate with the PV system?

The control center communicates with the PV system by a Modbus protocol and with the BESS by IEC 61850. The IEC 61850 data structures provided by the BESS were created beforehand by a configuration file. Fig. 5 presents a schematic of this structure. Fig. 5. use case “meeting the supply forecast”. 5.1. Constraints on implementation

Can a Bess be used with a battery energy storage system?

Measurements of battery energy storage system in conjunction with the PV system. Even though a few additions have to be made, the standard IEC 61850 is suited for use with a BESS. Since they restrict neither operation nor communication with the battery, these modifications can be implemented in compliance with the standard.

How is a PV system simulated?

The PV system is simulated on another PC system by a Modbus slave. A Modbus slave represents a server that supplies data through retrievable registers. The control center uses a Modbus TCP connection to query the system's current active power in regular intervals and compares this with the forecast's values, which are saved locally in the system.

How does a battery system work?

This is done by three systems: The Energy Management System (EMS) monitors grid demand and how the required energy can be transferred from the BESS. This is done through control logic. The EMS sends an input signal to either charge or discharge the battery based on the control logic requirement and the SOC of the battery system.

How does a battery energy storage system work?

Battery Energy Storage Systems (BESS) store energy during times of high production/low demand and then discharge it during times of low production/high demand. Like any energy source at a solar PV plant, BESS must be monitored and controlled. This is done by three systems:

When can large quantities of electricity be stored and retrieved?

Large quantities of generated electricity can be stored and retrieved anytime too little power is produced . Such a scenario can only be implemented when data is exchanged properly among a BESS, PV system and control system .

How can energy storage help a large scale photovoltaic power plant?

Li-ion and flow batteries can also provide market oriented services. The best location of the storage should be considered and depends on the service. Energy storage can play an essential role in large scale photovoltaic power plants for complying with the current and future standards (grid codes) or for providing market oriented services.

What are the energy storage requirements in photovoltaic power plants?

Energy storage requirements in photovoltaic power plants are reviewed. Li-ion and flywheel technologies are suitable for fulfilling the current grid codes. Supercapacitors will be preferred for providing future services. Li-ion and flow batteries can also provide market oriented services.

Are energy storage services economically feasible for PV power plants?

Nonetheless, it was also estimated that in 2020 these services could be economically feasible for PV power plants. In contrast, in, the energy storage value of each of these services (firming and time-shift) were studied for a 2.5 MW PV power plant with 4 MW and 3.4 MWh energy storage. In this case, the PV plant is part of a microgrid.

Which technology should be used in a large scale photovoltaic power plant?

In addition, considering its medium cyclability requirement, the most recomended technologies would be the ones based on flow and Lithium-Ion batteries. The way to interconnect energy storage within the large scale photovoltaic power plant is an important feature that can affect the price of the overall system.

Are photovoltaics and energy storage a sustainable future?

The integration of photovoltaics and energy storage is the key to a sustainable energy future. With falling costs and rising efficiency, these systems are becoming more accessible, paving the way for a cleaner, greener world. Adopting PV-storage systems today is a step toward energy independence and environmental stewardship.

Can flywheel energy storage be used in large scale PV power plants?

Nevertheless, flywheel energy storage are rarely found in current large scale PV power plants projects. Inertia emulation, fast frequency response and power oscillation damping requirements are strong candidates to be included in the future grid codes.
