Hybrid Microgrid Solutions

The Microgrid’s Command Center

The Cat Microgrid Master Controller (MMC) acts as the hybrid energy solution’s command center, coordinating the different energy sources and enabling them to work as a single entity. Managing every source in the entire system, the MMC ensures the community loads are connected in the most economical way. 

Cat MMCs Feature:

• Easy setup and operation
• Controller and ethernet reliability
• Protocol compatibility
• High-fidelity remote monitoring
• Large capacity on-site data storage

Total System Management

The MMC integrates a variety of traditional and renewable energy sources to provide overall monitoring and control of all connected hybrid energy solutions assets. They include:

• Graphical user interface for monitoring and control of complete system.
• Asset optimization to minimize the cost of energy.
• Grid import/export control when connected to the local utility service.

Caterpillar offers a choice of MMCs designed for industrial/commercial applications. They integrate a variety of traditional and renewable energy sources within a hybrid energy solution by providing optimized monitoring and control.

Traditional Power Generation and Renewable Liquid Fuels

Cat hybrid energy solutions enable seamless renewable energy integration with traditional power sources, such as on-site Cat generator sets. These generator sets can provide a much-needed backstop when renewable resources, including wind and solar, are not available.

Flexible Fuel Options

All Cat diesel generators can run on biofuels and have accommodated the use of biodiesel and hydrotreated vegetable oil (HVO) for over a decade. These fuels are available now and can help reduce lifecycle greenhouse gas emissions compared to diesel.

Cat gas generator sets can also run on a variety of lower-carbon intensity fuels depending upon the model. These include:

• Natural Gas – One of the cleanest burning fuels, natural gas can help you meet strict emission and environmental regulations compared to diesel.
• Biogas – Byproduct gases from agricultural, food processing, and industrial processes are captured to fuel Cat low-energy fuel generators.
• Hydrogen – Renewable hydrogen and blends of hydrogen and natural gas are among several alternative fuels to help achieve sustainability goals. 

Photovoltaic Solar Modules

Solar is one of the fastest growing sources of energy. This clean power source is readily available, without emissions or the need for traditional fossil fuels.

When incorporated into a hybrid microgrid, Cat advanced solar solutions help build resiliency with a renewable energy source. Converting sunlight into direct current to power microgrids, high-efficiency photovoltaic (PV) solar modules not only provide power during normal operations, but also feature technology to detect power disruptions and can operate in island mode.

Features and Benefits
