Solar container communication station EMS field requirements

4 FAQs about Solar container communication station EMS field requirements

How does an EMS communicate with a power conversion system (PCS)?

The EMS will communicate directly with the battery containers and Power Conversion System (PCS). The EMS will receive signals from the site SCADA systems, including Substation RTAC, TSO Equipment, MISO Meters Equipment, Owner provided equipment, MPC, and will monitor and send control signals as necessary to operate the BESS equipment.

What are the requirements for a communication interface of an ESS?

Fundamental requirements for a communication interface of an ESS can be found in existing standards such as IEC 61850-7-420 and Modular Energy System Architecture (MESA) (see Figure 5). Commercial systems often follow standardized communication protocols.

What are the components of a local EMS?

Just as an ESS includes many subsystems such as a storage device and a power conversion system (PCS), so too a local EMS has multiple components: a device management system (DMS), PCS control, and a communication system (see Figure 2). In this hierarchical architecture, operating data go from the bottom to the top while commands go top to bottom.

How does an EMS interface with a substation?

The EMS shall interface with the devices listed in Table 1. All device communication shall typically occur over Ethernet, CanBus or Serial, using DNP3 or Modbus. PCS acts as a bidirectional AC/DC converter the allow the batteries to charge and discharge from the grid. Meters in the substation.
