5. Energy scheduling

Plan curve:Users can configure their own electricity price templates based on local time of use electricity prices, set the charging and discharging power of energy storage during different time periods, and form a peak shaving and valley filling strategy template; Provide the function of configuring policy templates on a daily and weekly basis. Adapt to strategic operation in multi regional and multi price environmentspattern.

Demand control:By connecting a total meter to the low-voltage side of the transformer in the main incoming line, real-time demand values are collected. When the demand value reaches the limit value (which can be set), demand control is triggered. The system performs actions such as reducing charging, discharging, lowering the charging power of the charging pile, or reducing the adjustable load power based on the configured parameters for energy storage.

Dynamic expansion:By connecting a master meter to the low-voltage side of the transformer in the main incoming line, the transformer load rate is collected in real-time. When the transformer load rate reaches the limit value (which can be set), protection is triggered. The system performs actions such as reducing charging, discharging, lowering the charging power of the charging pile, or lowering the adjustable load power consumption based on the configured parameters.

Anti backflow control:By connecting the main meter to the low-voltage side of the transformer in the main incoming line, real-time reverse power data is collected. When reverse power occurs and reaches the limit value (which can be set), the system will perform actions such as settling, reducing discharge, charging, or photovoltaic power reduction on the energy storage according to the configured parameters. The implementation of the system's anti backflow strategy is software protection. If faster and more reliable protection is required, corresponding reverse power protection devices need to be added to detect backflow and immediately trip for protection.

Backup power function:During the operation of the system,ACCU-500The microgrid coordination controller executes the energy storage systemSOCProtect the energy storage system within the set limitsSOCOperate within a certain range and reserve a certain amount of power interval for backup capacity. The backup capacity can be customized and can provide emergency power to the load in case of power outage.

Others:Different strategies can be customized according to customer needs
