With OGEMA-based energy management systems, energy producers, storage and consumers can be specifically controlled. This makes it possible to make sensible use of self-generated energy in single or multi-family houses, to store excess energy and retrieve it later. In addition to basic management functions, the system allows the function as a gateway to the outside and can thus communicate with other participants in the future intelligent power grid. This allows OGEMA systems to make a contribution to supply stability through communication with the grid operator or to integrate them into a virtual power plant.
OGEMA supports these applications with a variety of existing communication interfaces especially for energy management and smart metering. The simple interface expansion also allows battery management systems and inverters to be connected. Domestic energy consumption can be achieved through various interfaces common in the building.
Integration of measuring points in energy management systems
Every provider of energy management systems for the ISO 50.001 knows the problem. His system must communicate with the measuring points installed at the customer. The large number of different device types and communication interfaces makes the connection to the energy management system in the cloud particularly difficult.
OGEMA provides remedy. Its modular concept makes it easy to plan, install, operate and maintain on-site data capture, including connectivity to the cloud. The built-in security mechanisms facilitate secure communication with the energy management system. Thanks to the app concept, measurement data can already be aggregated on site. So only the relevant information from the field of customer privacy is sent. If the customer wishes, he can also retrieve and visualize their measurement data directly in front of the respective consumer without an internet connection. This makes compliance with data protection and data economy requirements easy to do.
With OGEMA, such a system runs on a commercially available hardware platform. The configuration as well as the update can be done remotely over the network. If a meter replacement is necessary, simply replace the corresponding software module after the hardware replacement.
Further individual apps allow the customer an on-site evaluation of the accumulated data. By recognizing specific consumption patterns, it is even possible to monitor the condition of plants and provide the customer with early information on any necessary maintenance work.
