What is the standard procedures for conducting the Performance Monitoring for BESS system ?

By -

A brief on the standard procedures for Performance Monitoring of Battery Energy Storage Systems (BESS) that are to be followed for regular maintenance and to increase the life span of the system based on Indian and international best practices:

🔍 Standard Performance Monitoring Procedures for BESS

1. Battery Management System (BMS) Monitoring

  • Continuous tracking of:
    • Voltage (cell/module level)
    • Current (charge/discharge)
    • Temperature
    • State of Charge (SoC) and State of Health (SoH)
    • Thermal runaway indicators
  • Alarms and auto-shutdown if parameters exceed OEM-defined thresholds

2. Power Conversion System (PCS) Monitoring

  • Fully automated and unattended operation
  • Monitors:
    • Grid synchronization
    • AC/DC conversion efficiency
    • Fault diagnostics and self-protection features

3. Predictive Maintenance

  • Uses real-time data analytics to detect early signs of component degradation or failure
  • Key indicators:
    • Abnormal temperature rise
    • Voltage imbalance
    • Irregular current patterns
  • Enables preemptive servicing before faults escalate

4. Performance Benchmarks

  • Compare actual vs. expected:
    • Round-trip efficiency
    • Charge/discharge cycles
    • Energy throughput
  • Deviation triggers root-cause analysis and corrective action

5. Safety & Compliance Checks

  • Periodic audits for:
    • Fire suppression systems
    • Ventilation and gas detection
    • Emergency stop mechanisms
  • Third-party fire safety audits are mandatory under CEA draft regulations

6. Reporting & Logging

  • Automated logging of all operational parameters
  • Daily/weekly/monthly performance reports
  • Integration with SCADA or cloud-based dashboards for remote monitoring

Energy Conservation Building Code (ECBC): Enhancing Energy Efficiency in Domestic & Commercial Sectors

By -
Image
1. Introduction to ECBC The Energy Conservation Building Code (ECBC) was introduced by the Bureau of Energy Efficiency (BEE) under the Ministry of Power, India, based on the Energy Conservation Act, 2001. The ECBC serves as a regulatory framework to improve buildings' energy performance across India. With rising energy demand, especially in urban areas, energy-efficient buildings have become a national priority, which aligns with India’s goals for sustainable development and climate change mitigation . 2. Purpose and Objectives of ECBC The primary aim of ECBC is to reduce energy consumption in the construction and operation of buildings. This is done by promoting efficient design practices, materials, and technologies. Key objectives include: Minimizing energy consumption without compromising on the comfort and quality of life. Promoting the use of renewable energy systems such as solar photovoltaic (PV) and wind energy. Enhancing energy security and reducing dependency on fo...

What is P50, P52 & P90 ?

By -
P52, P53 and P90 are terms often used in the renewable energy sector, particularly in the context of wind or solar energy production analysis. These refer to statistical probability levels used in energy yield assessments to estimate the expected production of renewable projects over a certain time frame. P50 : Represents the median or "best estimate" production scenario. It means there is a 50% chance that the actual energy production will be higher or lower than this value. It is the expected average production in a typical year. P52 or P53 : These are uncommon notations, but they might represent slight variations from the median estimate, with a slightly higher probability of occurrence than P50. P90 : This represents a conservative estimate, meaning there's a 90% chance that the actual production will be equal to or exceed this value, making it suitable for financial risk assessments. In summary, P-levels like P50, P52, or P90 provide different confidence levels for ...

What is Kaprekar's constant ?

By -
Image
 6174 is known as Kaprekar's constant , a magical number in mathematics. The "magic" lies in a process discovered by the Indian mathematician Dattatreya Ramchandra Kaprekar in 1949. Here's how it works: The Kaprekar Routine: Take any four-digit number, using at least two different digits. (If the number has fewer than four digits, pad it with leading zeros to make it four digits). Arrange the digits in descending order and then in ascending order to get two four-digit numbers. Subtract the smaller number from the larger number. Repeat the process with the result. No matter what four-digit number you start with, after a few iterations, you'll always reach 6174 . Once you reach 6174, repeating the process will continue to yield 6174. This is why 6174 is often called a "self-repeating number" or Kaprekar's constant. Example: Start with 3524: Descending: 5432 Ascending: 2345 Subtract: 5432 - 2345 = 3087 Now repeat the process: Descending: 8730 Ascending...
