EMS (Energy Management System) function design

Real-time monitoring of power station operation

Function description:

The system monitors the components of the power station in real time, including the BMS system, PCS (energy storage converter) and load, ensuring real-time acquisition and recording of all key parameters.

Key points of implementation:

BMS System Monitoring:

Monitor total voltage, current, average temperature, SOC (power state), SOH (health state).
Record the charge and discharge current and power limits.
Focus on the minimum/maximum voltage and temperature of a single battery.
Collect fault alarm information and historical charge and discharge capacity.

PCS Monitoring:

Monitor DC branch voltage, current, power.
Monitor active power, reactive power, voltage, current, power factor, frequency, and temperature on the AC side.
Record the cabinet temperature, operating status, alarm information, and daily, cumulative charge and discharge.

Load monitoring:

Monitor voltage, current, active power, reactive power, frequency and other information of each phase.

Operation data of the power station

Function description:

Provides a user-defined interface to display real-time data and historical data, and supports report export.

Key points of implementation:

Design a user-friendly interface that allows users to freely choose which data to display. Historical data query function, support a variety of data formats (such as CSV, Excel, PDF) export.

Economic operation strategy of power station

Function description:

Based on energy storage and load ratio, the economic operation strategy of microgrid system is optimized.

Key points of implementation:

An analytical algorithm is used to evaluate the operating efficiency of PCS and inverters. Generate optimal operational strategies and execute optimization commands in real time.

Power station real-time scheduling and remote scheduling

Function description:

Configure data upload freely, and support scheduling between the field monitoring layer and the total control center.

Key points of implementation:

Allows the field device layer to adjust the uploaded data as needed.
Ensure data integrity and security during data upload.

Power station energy management

Function description:

Charge and discharge period is automatically controlled according to time period, load and electricity price.

Key points of implementation:

Real-time monitoring SOC, analysis of on-grid electricity price, load, control the direction of power flow.
Automatically plan charging and discharging strategies to maximize economic benefits.

Fault alarm

Function description:

Record and query events at all levels and manage them according to their importance.

Key points of implementation:

Establish the fault detection and alarm mechanism, and identify the event type by color.
Provides historical event query function, easy to trace and solve problems.

Report, real-time curve, energy flow display

Function description:

Provide real-time curve recording and statistics, support a variety of data analysis and display forms.

Key points of implementation:

Set different time intervals (5 minutes, 15 minutes, 1 hour, 1 day) for data recording. Generate customizable charts (graphs, bar charts) and export as Office or PDF files.

Data analysis

Function description:

A variety of data analysis tools are available to help users evaluate plant performance and energy saving potential.

Key points of implementation:

Realize the functions of energy flow chart, cost accounting, energy saving analysis and so on.
Provide energy consumption forecast and benchmarking analysis report to facilitate users to make decisions.

Operation benefit analysis of power station

Function description:

Through modeling, the economic benefit of the system is analyzed, and the overall efficiency of the power station is evaluated.

Key points of implementation:

The SOH of PCS output and energy storage system was comprehensively evaluated.
Provide detailed economic benefit analysis reports to help users optimize their decisions.
The EMS fully monitors the operation of the power station, optimizes economic benefits, and improves user experience. The flexibility and scalability of the system can effectively adapt to different environments and needs, and provide users with efficient and reliable energy management solutions.
