The data backup in the cloud provides quick and easy access to raw data from your systems. This allows customer’s internal IT to easily retrieve files and information for end users and to push it in another cloud infrastructure for more data accessibility and scalability.

For a fully integrated solution in VCOM, the day ahead as well as the intraday solar power forecast will be soon available in VCOM for a better estimation of the system performance in the short term.

Based on the current system performance, possible losses will be estimated and displayed as well for the respective system to enhance the efficiency in the O&M process and react on time for issues, avoiding further losses in the future.

• Solar power forecast available via the VCOM API
• Solar power forecast available as new chart in VCOM

It will be possible to have a detailed classification of the losses for a transparent evaluation of the system based on non-recoverable losses soon. For this purpose, our implemented machine learning algorithm makes it possible to identify systematic errors considering the historical measurement data of the system.

For systems which are curtailed by grid operators or even with Zero Feed-In limitation, a new Power Plant Controller (PPC) dashboard will summarize all power control relevant information at the point of common coupling as well as its effect on the performance of the system. Therefore the PPC dashboard will include new standard charts, tabular evaluation of the curtailment as well as effective reporting possibilities.

The added value by O&M teams should be reflected on the respective KPI formula based on the specific asset management contracts and transparently correlated to our ticket system.

For grid operators, solar traders and balancing service providers it becomes more and more relevant to get a better insight about the state and power capacity of renewable energy systems at any time. Therefore, blue'Log XC now provides the following real-time values about the weather situation and data about power levels to enable users to improve evaluations about site availability:

• Irradiation and ambient temperature
• Available active power
• Available reactive power
• Realized park restrictions by the grid operator
• Number of installed inverters
• Number of available inverters

Using the manual mode, the commissioning team can easily give manual setpoints and switch between the operation modes open loop and closed loop. The controller works without outages. At the same time the configurations for active and reactive power from the normal operation mode remain unchanged.

With systems in the commercial segment, there is often the problem that a measurement at the point of interconnection (POI) is not available and a retrofit of the current and voltage transformers is not economical. Therefore, the only approach for active power control requirements in closed loop is to measure at several points on the low-voltage side.

blue’Log combines and offsets the measurements of the existing meters and operates as a virtual meter. Since this solution is integrated in blue’Log, no additional hardware costs and no additional time delays in power control are to be expected.

The integration of renewable power systems into portfolios which contribute to balancing the grid is an ongoing process. For this, Transmission System Operators (TSOs) and Balancing Service Providers (BSPs) require real-time data and access to the power system. The blue‘Log provides the necessary interface. Its graphical user interface requires no programming knowledge and settings can be easily changed in the blue’Log frontend through parameterizing. As the monitoring and control gateway the blue’Log now supports the auxiliary services FCR and FRR including the following range of functions:

FCR – Frequency Containment Reserve Provision of FCR by switching to Frequency Sensitive Mode (FSM) in compliance with Network Code on Requirements for Generators (RfG) Monitoring frequency measurement at the point of interconnection (POI) Configuration of FSM characteristic curve with graphical assistance Automatic control in case of grid unbalance FRR – Frequency Restoration Reserve Provision of FRR by receiving and executing external control setpoints from Balancing Service providers (BSPs) Irradiation, system availability, available power estimate calculation and other measurements at the point of interconnection (POI) in real-time

The graphical overview contains all configured blue’Log XM/XC interfaces. This allows you to quickly and easily identify for which function the interface is configured and its state or actual/live value. For sensors that are connected to analog inputs you can also check the electrical value. This is very useful when you want to identify if a sensor or cabling is damaged.

If there is no internet connection available because of errors in the network, simply not ready yet during commissioning or because of security reasons, firmware updates can be implemented offline via USB drive.

For service reasons or in case of emergency you may want to stop all PV inverters of a system as fast as possible. With blue’Log XC you can do this with just one click via remote or local. Afterwards, you can easily start the system with the same options and efficiency.
