At Hannover Messe later this month, intelligent software provider RTSoft will be presenting the Amigo advanced microgrid optimisation, vendor-independent and fully scalable network management software for the automatic control of individual microgrids in medium and low voltage structures.
 
A focus of German company RTSoft's presentation at the joint stand of the Bavarian Energy Technology Cluster (Cluster Energietechnik) lies in the optimisation of microgrid operation in industrial enterprises with the goal to improve power quality, feed-in profits and reduce energy, maintenance and repair costs.
 
In the industrial microgrid showcase visitors will be able to change settings of the virtual microgrid via Amigo's scada interface and see how simulation changes according to the selected scenario.
 
Amigo’s control algorithms are used wherever energy is generated, stored, distributed and consumed locally as an addition to the standard feed-in from high and extra high-voltage grids. Applications can be found wherever microgrids are emerging, from e-mobility charging stations, and facilities with combined photovoltaic installations and block heating power plants to public utilities supplying conurbations or large rural areas.
 
The software monitors, controls and manages low and medium voltage (1 to 60kV) microgrids autonomously and without human intervention. It coordinates distributed energy resources and storage systems, reactive power controllers (volt-VAR controllers), and demand response units. This lets users reduce the influence of external networks, lower tariffs through peak load management and lower maintenance costs by improving the reliability and quality of their network control in terms of active power, frequency, reactive power and voltages.
 
In addition, they can raise extra revenue from active load frequency control services and achieve network capacity savings through the integration of active demand response management.
 
Unlike conventional medium voltage network control technologies, it provides configurable logic for rule-based, automatic control of local heterogeneous resources and consumers. Compared with previously available grid control technologies for municipal utilities and industrial applications, it has a modular design and an open system architecture without vendor restrictions, which can lead to lower operating costs.
 
Because Amigo is designed for microgrid control of entire cities, the intelligent network management software can easily control multiple substation microgrids including volt-VAR control as well as flisr (fault location, isolation and service restoration) functions. Likewise, aggregators of distributed energy resources can profit from the use of Amigo and maintain virtual power plants. Island systems without connection to a public power grid are also possible.
 
The scalable management and control software runs on central servers or remote controllers in the microgrid. The smart scada server connects generators, energy storage, uninterruptible power supplies, smart meters and other microgrid peripherals via common remote sensing protocols such as IEC 61850 and IEC 870-5-1-101/103/104 or OPC and Modbus.
 
The core modules of the microgrid control system include AGC (automatic generation control) and V/VC (automatic voltage and reactive power control) modules as well as numerous modules for planning, analysing and optimising resource usage, load flow and connection to superordinate electric power transmission networks as well as self-diagnostics.
