Main components of the Omnivise Hybrid Control solutionThe Omnivise Hybrid Control solution consists of three main components:
Microgrid Controller SPPA-T3000 hardware
The Microgrid Controller of the Omnivise Hybrid Control solution is based on the Siemens Energy standard plant control hardware SPPA-T3000. This ensures highest hardware standards in reliability, longevity and security.
SPPA-T3000 includes AS3000 Automation Server, and CS3000 Communication Server hardware modules. It is designed for a wide range of applications and for rough environment conditions.
Full redundancy and cyber security functions are provided on a hardware level.
The innovative, flexible platform combines all automation and communication tasks. It provides real time capabilities as needed for demanding control and closed loop applications. Also, T3000 provides the runtime environment for demanding and complex optimization and programming tasks. An integrated dual redundancy link allows smaller footprinting and reduced wiring. The integrated 3rd party connectivity enables an efficient control system design with a scalable setup for easy expansion. Additionally, online repair can be performed with only a temporary interruption of the redundancy. I/Os are connected via PROFINET and/or via PROFIBUS.
SPPA-T3000 provides flexible connectivity options, e.g.:
• Modbus RTU/ASCII and TCP
• DNP3.0 serial, over UDP2 and over TCP
• IEC 60870-5-101 and -104
• IEC 61850
• Connect S7/PCS7 via Black Box
• OPC UA Client (DA, AC)
SCADA Application Server
Omnivise Hybrid Control SCADA running on the application server gives operators and engineers full control and transparency over the microgrid. The solution is preconfigured with standard microgrid dashboards showing all necessary information, with several levels of detail.
- System overview with monitoring and alarms
- Single-line-diagram overview
- Detailed asset control and monitoring
- E-BoP Balance of Plant
- Manual operation and control over all individual assets
- Data archiving
Key features of Dispatch Optimization
- Sets the basis to connect market-driven trading, including spot markets, with the defined production potential of the fleet and its plants
- Generates short, medium and long-term generation schedules and provides recommendations for cost and revenue-optimized generation
- Supports fulfillment of supply obligations with optimized use of fuel or other resources
- Also provides information to help support decision-making for fuel contracts, electricity contracts, CO₂ planning, investment calculations for determining whether to add capacity or upgrade existing plants
Omnivise Hybrid Control: Use CasesPer definition and standards, microgrids are entities which manage their own decentralized power production and consumption and are capable of island operation mode.
Depending on a business case, many microgrids, always run in on-grid mode. Managing a microgrid with multiple different decentralized resources requires a hybrid microgrid controller to provide automated and at the same time optimal operation for the customer.
Omnivise Hybrid Control is the perfect solution for large and mid-size microgrids, e.g., for IPPs, islands, industries, data centers, mines.
Islands and remote areas with high renewable penetration
Integrating large amount of renewable resources (PV, wind) on islands and remote areas which rely on conventional diesel generation can reduce overall fuel and operational costs.
This however requires integration of additional energy storage (batteries, H₂) in a microgrid to ensure the reliable and stable power supply.
Possible use cases:
- Smoothing of intermittent renewables (PV, wind) to inject into the grid of an island under ramping constraints
- Diesel fuel offsetting by shutting down diesel gensets when renewables are available, and running them when not
- For long term storage needs green hydrogen production
- H₂ electrolysis -> H₂ storage -> power
Integrating renewable generation with CCPPs for decarbonization
Renewable resources (PV, wind, green H₂) and batteries can be well integrated with existing and new combined cycle power plants in a microgrid to reduce the carbon footprint and increase the overall system efficiency.
Possible use cases:
- Providing resiliency with off-grid capability with integrated PV and BESS
- Ancillary Services – frequency and voltage grid support with BESS and H₂
- CO₂ reduction with PV and BESS while keeping low ramping of CCPP for higher efficiency
Industrial Microgrid for Resilience and Cost Savings
With increasing cost of electricity and at the same time demand, C&I customers can install own generation to reduce their energy bills, and at the same time be able to run their essential load in off-grid mode. With CHPs and CCPs thermal energy is extracted for industrial processes, heating/cooling or electricity recuperation. With integration of rooftop PV, CO₂ emissions are reduced.
Possible use cases:
- Peak shaving for TOU tariff and demand charge savings with own generation (PV+BESS, gas, diesel)
- Increased efficiency with thermal energy extraction (CHP)
- Resilience in avoiding blackouts and off-grid operation
- CO₂ reduction
Our hybrid control solution successfully runs Isabela Island Hybrid Power Plant since 2018. The solution supplies almost 900 households with electricity, on Isabela, the largest Galápagos Island. It helps to eliminate the use of fossil fuels by integrating renewable resources to address the energy challenges of the island.
The controller manages the hybrid power plant by integrating a 952 kWp photovoltaic system, a battery storage system with an output of up to 660 kW and a generator power plant with a total output of 1625 kW.
