Hybrid Microgrids

The basic concept is simple. Wind or solar energy reduces reliance on power produced from generator sets, saving fuel and, to a lesser extent, maintenance costs. The generator sets firm the renewable sources and follow the load. Sophisticated digital controls tie the system together. Energy storage enhances system economics and helps the generator sets respond smoothly to significant fluctuations in output from the renewable resources, while maintaining consistent voltage and frequency.

Today, there are several industrial sites worldwide with on-site generation and islanding capability. The main reason for these constellations usually is the requirement for process optimization in a certain industrial site. For example, huge amounts of steam are required for chemical processes. In this case the process owner can decide to install its own steam turbine-based generation, which will increase power supply reliability and reduce the cost of energy.

Microgrid Financing

State regulatory bodies are realizing that out-of-date regulatory rules are limiting Microgrid adoption and are working to change regulation. States such as New York, Connecticut, and Minnesota have allocated funding and started conversations on how best to change the state regulation to allow for Microgrids to be adopted.

Energy Modernization through Microgrids

A microgrid is a discrete energy system consisting of distributed energy sources (e.g. renewables, conventional, storage) and loads capable of operating in parallel with, or independently from, the main grid. The primary purpose is to ensure reliable, affordable energy security for commercial, industrial and federal government consumers. Benefits that extend to utilities and the community at large include lower greenhouse gas (GHG) emissions and lower stress on the transmission and distribution system.

Microgrids New Potential

In recent years, new technologies have also come to market. These new technologies allow modern “smart” microgrids to provide benefits exceeding those of their predecessors, and are spurring renewed interest in microgrid development. As renewable energy becomes more reliable and the capacity of new battery-based stored energy systems increases, microgrids are now viewed as a viable way to meet demand when production of intermittent renewable sources like wind and solar energy is low.

Introduction to Microgrids

Network downtimes, natural disasters and external attacks are just some of the reasons why a grid-connected facility may need to become temporarily independent. ABB‘s microgrid solutions enable a smooth transition to “islanded” mode, continually supplying stable, high-quality power with 100 percent peak renewable penetration. ABB is the pioneer and world-leader in microgrid solutions.

The Energy Efficient CHP Microgrid

This Microgrid Knowledge Special Report paints a picture of the emerging microgrid-driven world, with Combined Heat and Power (CHP) at its core. For a long time CHP and District Energy seemed like the best-kept-secret of energy insiders. Learn how CHP and District Energy are the keys to building the world’s most energy efficient microgrids.

NRG: Renewable Energy

As renewable energy solutions take hold, a natural offshoot is that becomes easier for new companies to visualize how a solution can work and more efficient to implement them. In other words the process to identify, visualize and embrace renewable energy is now quicker and more self-evident that ever. Another factor is the range of solar technologies and approaches now being put in place.

Energy Efficiency with Mighty Microgrids

The economic case for microgrids grows as the cost of distributed generation and energy storage continue to fall. Some companies already offer turnkey “nanogrids” that serve a single building. Larger, community microgrids are also being built, testing out the technology, and the business and legal models. A few states such as New York and California are changing the rules and offering funding to accelerate development of microgrids.
