function introduction of integrated pv-storage intelligent control solution
the "integrated pv-storage" (photovoltaic-storage integration) refers to a small-scale self-supply power system composed of distributed photovoltaic (pv) systems, electrical loads, power distribution facilities, monitoring and protection devices. it can also be called a microgrid. combined with pv-storage monitoring and management, it improves the efficiency and safety of equipment operation, and can play roles such as "negative load regulation, electricity storage, supporting new energy grid connection, compensating for line losses, power compensation, improving power quality, off-grid operation, and peak shaving and valley filling".
core functions
pv monitoring
supports time-periodic query of the variation trends of power generation and solar irradiance over time, as well as the variation trend of electricity generation over time. it allows switching the query mode between trend chart and list, and provides an overview query of accumulated revenue, daily revenue, real-time power generation efficiency, total electricity generation, daily electricity generation and real-time power.power prediction
supports prediction of solar irradiance and power generation for ultra-short-term (next 4 hours), short-term (next 3 days) and (next 7 days), as well as comparison between predicted values and actual values.battery monitoring
supports overview of battery health status, voltage and current values; location-based query of battery values, battery serial numbers and temperature; custom time-period query of historical voltage and current variation trends over time, and viewing of charging and discharging history records.energy storage strategy control
supports custom configuration of energy storage strategy control schemes, modification of scheme activation status, modification and editing of existing schemes, and configuration of strategy parameters for automatic detection and configuration of charging and discharging strategies.health status analysis
supports custom time-period query of discharging and charging behavior analysis, specific statistical analysis of charging and discharging behavior, and chart switching to view charging and discharging events.
integrated pv-storage intelligent control framework
case in power industry
a certain company is the main entity for regional power grid operation and trading in yunnan province. it undertakes the tasks of transmitting electricity from western china to eastern china and sending electricity to vietnam and laos. it is an important enterprise in yunnan province for implementing the "west-to-east power transmission", "yunnan power export" and fostering the power support industry. in 2017, it completed a total electricity sales volume of 221.25 billion kwh.
relying on the integrated pv-storage intelligent control solution, the company has established a long-term cooperative relationship with power grid companies by virtue of its high-quality, high-performance and high-stability voltage monitors. at present, it has cooperated with 11 local power supply bureaus in the province. in 2015 alone, the procurement order for voltage monitor products reached nearly 4,500 units, which fully demonstrates the recognition and affirmation of the company by power grid companies.
