BESS

Energy storage systems using battery storage (BESS) offered by Cover Energy Plus include an energy storage system based on various types of batteries (АКБ), a centralized management system (EMS), a power management system (PMS), a power conversion system (PCS), and a battery management system (BMS).

– EMS is implemented for comprehensive control and management of the BESS system.
– PCS functions as an interface between the batteries and the grid, ensuring bidirectional energy flow.
– PMS provides coordination for multiple PCS and is used to implement predefined management scenarios.

The proposed solutions for managing and automating BESS support different types of batteries such as lithium-ion, lead-acid or lead-carbon, sodium-sulfur, and others, from various manufacturers.

Energy storage systems play an important role in balancing the energy system. The ability for power plants to store generated electricity in BESS provides flexibility to the energy system, while also smoothing out power fluctuations associated with renewable energy generation.

Thus, having power plants with their own, or access to leased, BESS capacity will allow renewable energy in Ukraine to develop at a faster pace while minimizing risks to the operational safety of Ukraine’s integrated energy system.

The proposed BESS solutions for power plants enable the achievement of the following goals:
– Stabilization of the integration of renewable energy sources and improvement of electricity quality;
– Smoothing out power fluctuations from renewable energy sources;
– Balancing the system at the level set by the dispatch center;
– Effective frequency regulation, voltage control, and peak load limitation.

Large-scale energy storage systems are used for peak load limitation, backup power supply, deferring investments in generation facilities, and for transmission and regulation of frequency or voltage within the energy system. In addition, such a system enables the rapid startup of reserves and island operations, ensuring continuous power supply to critical loads in the event of a temporary disconnection from the transmission and distribution network.

Features:
– The EMS incorporates integrated functions, including electrical monitoring, energy management, and auxiliary monitoring. Enhanced functions include peak load limitation, frequency regulation, voltage regulation, cold start, and oscillation damping.
– Synchronous coordination capability for managing hundreds of PCS.
– The coordination management system employs a hierarchical control structure and high-speed fiber-optic communication, utilizing the IEC 61850 protocol.
– The monitoring network and the coordinated management network are independent, ensuring reliable operation of group control and regulation of PCS.
