BESS Operational Resilience and Lightning Protection
Battery Energy Storage Systems (BESS) store energy from the grid or renewable sources. BESS consists of rechargeable batteries, power conversion systems, and control systems. They stabilize the grid, manage peak demand, integrate renewable energy into the grid, and provide backup power. Large BESS systems have a capacity of more than 3,000 MWh / 750 MW.
Traditionally, Lightning Protection Systems (LPS) are designed to reduce the probability of catastrophic events on BESS. At Scientific Lightning Solutions, we take a comprehensive approach that protects BESS against catastrophic losses and significantly improves operational resilience against direct and indirect lightning strikes.
Operational resilience against lightning is crucial for BESS to ensure uninterrupted operation and prevent damage or downtime. Key factors for BESS operational resilience against lightning are:
- Design Considerations: BESS should be designed with lightning protection measures integrated into their overall design. This includes considering the BESS location, environmental conditions, and lightning strike risks.
- Surge Protection Devices (SPDs): They are essential to safeguard BESS components against transient voltage surges caused by lightning strikes. SPDs mitigate the risk of equipment damage.
- Grounding Systems: Effective grounding systems are fundamental for dissipating lightning energy safely and efficiently into the ground, minimizing the risk of electrical damage to BESS components.
- Isolation and Shielding: BESS components, such as batteries, inverters, and control systems, should be isolated and shielded to minimize the risk of electromagnetic direct or induced transients from lightning strikes. This helps maintain system integrity and operational stability.
- Monitoring Systems: Monitoring lightning activity enables proactive measures to protect BESS operations. Real-time monitoring of lightning activity allows operators to implement shutdown procedures or activate protective measures when necessary.
- Maintenance and Inspections (M&I): Scheduled (M&I) of BESS and LPS components are critical for identifying potential vulnerabilities and ensuring continued operational resilience. Routine maintenance helps detect and address issues before they escalate into operational disruptions.
- Training: Educating personnel on lightning safety protocols and emergency response procedures enhances operational resilience by ensuring staff can respond effectively to lightning-related risks. Increasing personnel’s awareness of lightning hazards and mitigation strategies strengthens the overall resilience of BESS operations.
By incorporating these factors into BESS installations’ design, operation, and maintenance, operators can enhance their resilience against lightning-related threats and maintain reliable and continuous operation.
