Hybrid EMS

Orchestrate the future of renewables

The market for hybrid energy systems is expanding rapidly. Energy generation, storage, and consumption technologies are being combined into a single system managed by a central control component.

For scenarios which combine renewable energy production systems and battery storage, this central component is a Hybrid Energy Management System (Hybrid EMS), which orchestrates the complex flow of energy within the system.

The Hybrid EMS from meteocontrol is specifically designed for scenarios combining PV production with battery storage or using standalone battery storage. The Hybrid EMS solution orchestrates the complex flow of energy within your system, ensuring seamless integration with a single grid connection point.

The “Hybrid EMS license blue’Log^® XC”, is a software extension that enables your blue'Log^® XC to optimize your energy generation and consumption based on your needs and local grid connection requirements.

More information

PV self-consumption

This feature is commonly used in commercial and industrial settings to meet the energy demands of local loads, e.g. large consumers, using electricity generated on-site by PV systems.

The integration of a battery means that the bulk of required energy is generated on-site, resulting in significant savings in electricity costs. Hybrid EMS efficiently manages this process, ensuring that PV power is only supplied to the grid after the local load is met and the battery is fully charged.

Zero feed-in

In areas with limited grid connection capacities, grid operators often require new plants to consume most or all of the electricity they generate. This restriction limits the amount of power that can be fed into the grid.

Hybrid EMS ensures compliance with this limit by curtailing PV power only when the local load is covered and the battery is fully charged.

Band shaving (e.g. peak shaving)

In industrial settings, power-based electricity prices can drive up the total cost of electricity. Hybrid EMS can be configured such that peak loads are “shaved” by the battery system.

To guarantee low electricity costs, the battery only discharges once the power at the grid connection point falls below a certain predefined threshold. Similarly, you can also manage the maximum feed-in power by configuring a threshold beyond which the battery will store excess PV power.

Setpoint control

Hybrid EMS can receive and implement external active power setpoints from grid operators to maintain grid stability. If a grid operator sends a curtailment command, the excess PV power is not simply “wasted”; instead, it is stored in the battery for future use. The setpoint commands can be received via digital inputs, or analog inputs, or Modbus.

Energy trading

Energy traders can remotely control the hybrid energy system via a dedicated interface, allowing your system to pariticpate in intra-day and day-ahead auctions. The Remote Power Control (RPC) license is required to unlock this interface.

Reactive power control

In addition to managing active power, Hybrid EMS can also contribute to voltage stability by supplying reactive power at the grid connection point. Reactive power can be controlled by methods including Q(V), Q control, power factor control, and others. You decide whether the reactive power demand is primarily met by the PV system or the battery.

FAQ

You have the questions, we have the answers. There is already a lot of interest in Hybrid EMS, so we want to answer important questions right away.

Which Battery Energy Storage Systems (BESS) are already compatible with the Hybrid EMS?

Already now, a wide range of BESS is compatible with the HEMS. Please refer to our compatibility list for our blue'Log XC. If you are missing a compatibility, please contact our sales team. Our development team is always working to ensure that the list is constantly expanded.

How can an existing blue'Log XC be extended to a Hybrid EMS?

Hybrid EMS is a license extension for the blue'Log XC. It can therefore be retrofitted to an already installed blue'Log XC via a software update.

Can Hybrid EMS be integrated into existing PV systems or battery storage systems?

Yes. Since Hybrid EMS is a license extension for our blue'Log XC, it can be conveniently integrated into an existing PV system or battery storage system.

What are the advantages of a hybrid energy management system compared to a conventional PV system or a stand-alone battery system?

Through Hybrid EMS, energy generation, storage and consumption technologies can be combined into a single system and managed by a central control component. At the same time, Hybrid EMS optimizes energy generation and consumption based on your needs and local grid connection conditions. You avoid higher electricity costs or get maximum self-generated energy from your PV system. Apart from this, Hybrid EMS can also be used for battery-only storage systems.

How does Hybrid EMS handle excess energy production from the PV system, and can it feed it into the grid?

This depends on the configuration of the Hybrid EMS. Excess PV energy can be fed into the grid or supplied to the battery. A regulation of the PV system is also possible.

Can Hybrid EMS be used to control reactive power as well as active power?

Yes. All functions for reactive power control, which are already implemented in blue'Log XC, can also be used with Hybrid EMS without restrictions. Thus, the reactive power can be provided grid-compliant at the grid connection point.

Can Hybrid EMS also be used for battery standalone system?

Yes, this is possible.
