Renewable energies are becoming a major part of the power generation mix. But these resources are depending highly on environmental factors. AEG Power Solutions helps customers to make the most of them by shifting the power generation to the most profitable times or aligning it with consumption peaks. Battery energy storage also keeps the production within the grid stability requirements.
Through the increasing number of fluctuating renewable energies, grid operators are facing more and more difficulties to keep the grid stabilized. Grid frequency and voltage have limited operating areas and have to be continuously regulated to guarantee the grid stability. Furthermore renewables cause power peaks which can exceed the grid's capacities. A backup storage will here save costs and will give you more flexibility.
Load management or demand side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. Load management allows utilities to reduce demand for electricity during peak usage times, which can reduce costs by eliminating the need for peaking power plants.
The concept of a residential energy storage system has captured the imagination of the growing ranks of stakeholders with interest in electricity storage. It involves a central battery energy storage system that is located at the periphery of the utility distribution system near residential areas. The system can ensure the power supply of connected houses (UPS functionality) or can help to maximize the solar energy self-consumption rate. It also supports utilities by stabilizing the local grid.
Grid linked micro grids offer three primary benefits for utilities (DNOs) and transmission network operators (TNOs):
- protecting the macrogrid from the microgrid (eliminating fault current contributions)
- allowing the microgrid to maintain power seamlessly during a macrogrid outage (uninterruptible power supply operation)
- qualifying the microgrid as a least-cost solution for DNOs/TNOs to maintain grid stability (e.g. voltage/frequency control)
Battery energy storage solutions for off-grid are designed primarily for use in “sun-belt” countries with extremely high solar radiation. AEG PS battery energy storage solutions focus on combined PV / energy storage turnkey projects for the provision of basic levels of electrification and for fossil fuel efficiency measures in remote areas.
Operators of industrial power grids face two major challenges: They need to optimize their average production costs –including reducing CO2 emissions – and at the same time ensure a secure and reliable power supply for production. The use of renewables to supply industrial facilities reduces both CO2 emissions and the requirement for imported electricity. This lowers operating costs, especially since surplus electricity can be sold. If storage systems are used, it allows operations to take the form of an electrical island, ensuring smooth production, regardless of a public power supply that in many locations may be insufficient.
