Solution package for the monitoring and control of distributed energy resources for economically optimized and reliable operation of power system.
Together with SCADA/DMS/EMS systems, Distributed Energy Resource Management (DERM) systems are important monitoring and control facilities for dispatch centres, and play key roles in operation of power systems with high penetration of distributed resources. These systems are necessary for the support of dispatching jobs with distributed energy resources (DER) to ensure economically optimized and reliable operation of the power systems.
Our @DERM™ is designed to ensure the proper operation of distributed renewable energy resources in accordance with technical requirements of distribution and transmission networks. The solution also allows for Virtual Power Plant (VPP) operation, which can improve participation and cost-effectiveness of DER in the electricity market. The system is well-suited to the management of roof-top solar farms and other DERs.
ECONOMICAL AND RELIABLE SOLUTION
for Customized Configuration
Compliance with National &
International Grid Code
Maintenance Cost Optimization
- Provide tools for collection of important operation status data of renewable equipment, including system data, metered data, status of integrated control devices, alarming, etc., in real time and through standard interconnection protocol. In addition, these tools can share information with SCADA systems at dispatching centres and power companies, as well as can be used for making necessary control requests.
- Highly suitable for roof-top solar power management as well as for integrating other renewable energy sources such as wind turbines, small hydro power plants, etc.
- Manufacturer-independent, suitable for controlling power plans operating inverters, turbines, and other equipment from various vendors.
- Ready for future utility interface bus integration.
- Allow dispatching centres to fairly allocate generation output under conditions of system curtailment.
- Allow flexible operation of various DERs to avoid overloading while maintaining power quality for the local grids.
- Support various control methods including: control by AGC from SCADA/EMS system; control by generation schedule; control by manually-set parameters; and calculation and redeployment of distributed sources in case of limitation applied on transformers and line feeders to prevent overload.
- Support various control functions including: active power control; reactive power control; ramp rate control; power factor control; voltage control; plant startup/ shut-down; as well as grid support control such as limit active power and power reserve, voltage profile monitoring and control, reactive power adjustment to maintain grid voltage at connection point, grid frequency support, fault-right through support, etc.
- Provide the tool for optimum generation commitment in the market with transparency, safety and national energy security.
- Decrease frequency of generator shut-down/ start-up for those units with high start-up cost and long start-up time (coal thermal, gas turbines), enhance system reserves, avoid oil thermal unit commitment for peak load and reduce overall system operation cost.
- Forecasting of power generation output of DERs are more accurate due to the smoothing effect when combining large number of DERs
- A large number of DERs, storage systems as well as controllable loads can be assembled into a single, adjustable power unit (a Virtual Power Plant) with rated power and performance characteristics equivalent to a traditional power plant.
- Help DERs flexibly respond to price signals in the electricity market, accurately forecast their own generation schedule, and reduce the imbalance between generating capacity and load demand in the power system.
