Renewable Energy

100% Renewable by 2050
This week, the U.S. Department of Energy (DOE) and the Federal Emergency Management Agency (FEMA) released a one-year progress report on their on-going investigation into Puerto Rico’s electrical infrastructure. The report suggests that the island should begin heavily investing in renewable energy, specifically in small-scale, distributed solar power.

Battery Energy Storage

The largest battery storage project in Brazil, a 30MW/60MWh system, was inaugurated last year and presents a significant milestone in the country's energy infrastructure. Here are the key details about this groundbreaking project:
1. Project Overview:
• Capacity and Inauguration: The system has a capacity of 30MW/60MWh and was inaugurated on the networks of transmission system operator (TSO) ISO CTEEP.
• Investment: The project required a total investment of US$27 million, with ISO CTEEP permitted by regulations to earn up to US$5 million in revenue from the asset each year.

2. Impact and Purpose:

• Increasing Hosting Capacity: The BESS will help increase hosting capacity to cope with an expected increase in demand on a congested network. This enables the TSO to defer investing in a more expensive traditional transmission line.
• Non-Wires Alternative: The project serves as a 'non-wires alternative' or storage-as-a-transmission asset, demonstrating innovative approaches to enhancing grid capacity and reliability.
• Reducing Fossil Fuel Reliance: It aims to reduce reliance on fossil fuel peaker plants, which are often polluting and expensive, despite their infrequent use.
3. Location:
• The plant is located at an ISO CTEEP substation in São Paulo.

 

CHP and Microgrid

CHP can be a key resource to use in a microgrid because it provides a reliable, continuous, and controllable baseload source of electricity and localized thermal energy. Until energy storage allows renewable energy sources to be cost-effectively and reliably available on a continuous basis, CHP will continue to be a valuable resource, allowing renewables to serve peak daytime loads and support utility grid operations.

A profitable partnership.

These mutually compatible technologies come together to be more efficient, more cost-effective, more profitable, and more useful than they are on their own. 

• A CHP system linked with a microgrid allows the customer to utilize electrical energy and the thermal energy (hot water, steam, or chilled water) produced by the microgrid's power generation system.
• Increases overall efficiency, especially in the consumption of fuel feeding the microgrid's power generator.
• Reduces net operating costs. CHP often forms the most economical anchor for a microgrid system.
• Energy provided by the CHP can help with load balancing or add to energy storage. Battery Storage can keep CHP running at the most efficient conditions

 

Combustion Performance Optimization

Combustion Performance Optimization

Sunco International Inc's energy technology applications include intelligent combustion optimization software:  expert system, neural network systems and optimization algorithms combined into a program that runs under a Windows operating system. Boiler combustion optimization is used to identify combinations of control settings that achieve optimum heat rate, minimum NOx emissions or other important goals of plant operation.

What intelligent combustion optimization software can do?
This AI Software is used to guide the plant engineer through a series of parametric boiler tests which gather a database to characterize boiler operations over a wide range of conditions. The software then analyzes the data and identifies optimal boiler operating conditions. The recommended control settings are typically used to obtain the desired NOx levels while achieving the lowest possible unit heat rate.
　　
Optimization process:
• Preliminary test for calibration of instruments, equipment maintenance and make the necessary adjustments
• Pulverized coal combustion system is adjusted to reduce air an coal imbalances and improve mill performance
• Installation of new, advanced diagnostic instruments as required, providing key data for improved combustion optimization: Furnace Gas Exit Temperature (FEGT) probes, online fly ash LOI analyzers, and furnace camera thermography technology.  Data from these advanced diagnostic tools can be incorporated into the optimization software and used in determining optimal boiler settings
• Parametric tests are conducted using the optimization software to determine the optimal boiler control settings. These tests are carried out over the load range and provided the data needed to specify key parameters such as overfire air damper setting, economizer O2 level, burner air damper settings and burner tilt angle as functions of load.
• Analysis of test data and modeling to incorporate algorithms into the optimization software
• Development of software user interfaces with the boiler model integrated into the software.  The control system is then configured by an on-site installation software consultant
to permit automatic operation at these optimized settings.
• Conduct on-site verification testing of the software by varying boiler control settings.
• Training of operating personnel for typical optimization objectives: 　　
• Optimum heat rate 　　
•  Minimum NOx emissions 　　
•  Minimum mercury emissions 　　
•  Reduced furnace slagging and convection fouling 　　
• Reduced unburned carbon in fly ash 　　
• Steam temperature near design value
