ACCU-100 Microgrid Coordination Controller

Name: ACCU-100 Microgrid Coordination Controller
Brand: Acrel Co., Ltd.

ACCU-100 Microgrid Coordination Controller Function:

1) System Overview: Realize the functions of collecting, monitoring, visualizing, abnormal alarming and benefit

statistics of photovoltaic, wind power, energy storage, load, charging pile and environmental data of microgrid.

2) Equipment Monitoring: Realize the monitoring of power generation, power consumption, charging and discharging

status of photovoltaic components, inverters, PCS, BMS, charging piles and other equipment, and support event query,

statistical report and other functions.

3) Power Forecast: Realize photovoltaic short-term and ultra-short-term power forecast, and perform error analysis.

At the same time, for all loads in the microgrid, based on historical load data, through big data analysis algorithm,

predict the load power curve.

4) Optimization control: Coordinate photovoltaic, wind power, energy storage, load and other energy entities to

dynamically plan intelligent strategies to achieve coordinated control of energy storage and photovoltaic, such as

planning curves, peak shaving and valley filling, anti-reverse flow, new energy consumption, demand control, etc.

5) Economic dispatch: According to the prediction results of photovoltaic and load power, combined with the

interactive power of the power grid of time-of-use electricity price, energy storage status and constraints,

with the goal of low electricity cost, an economic dispatch model is established, and a deep learning algorithm

is used to analyze the microgrid operation power plan. The system decomposes the power plan to achieve photovoltaic

and energy storage.

6) Energy analysis: It has microgrid energy consumption and benefit analysis, microgrid economic operation analysis,

multi-dimensional power analysis, and provides a basis for intelligent operation and maintenance.
