These are very small systems that are typically houses or small institutions. They provide basic electrification via a small power hybrid system that covers essential needs such as the lighting requirements of a household, and other essential services. If connected to the grid, the hybrid system will require an islanding device to physically disconnect from the grid and serve the committed load in case of an outage.
Nano Hybrid Power Systems
Let's start first by defining what microgrid means. The answer depends on whom you are talking with.
Microgrids refer to a small-scale power supply network of one or multiple power generation sources, and loads that are or not grid-connected with a power range from a few kilowatts to megawatts in size.
Depending on the size and the end-users, microgrids fall into three categories:
Residential - This is a low voltage network that will typically include PV solar, a plug-in electric vehicle, energy storage, and home integration.
Commercial and Industrial - This is a low voltage with renewables, combined heat power (CHP), energy storage, and load management.
Utility-Scale - This is medium voltage -distribution, interconnected with solar, wind, energy storage, and power generators.
Pacific Energy works with every end-user to create a safe, cost-effective, and efficient solution that matches their exclusive needss.
With the emergence of PV solar as one of the cheapest sources of energy, most cost-effective and reliable energy storage, along with new power electronics capabilities; hybrid power systems are recognized as the smartest solutions, propelled by and for our digital and sharing economy.
Microgrids come in all types, all sizes. They mix renewables with more traditional power sources to generate cleaner, more sustainable and more reliable power to serve local loads. They are found in residential properties or areas such as large cities and off-grid rural communities. They also supply remote industrial sites, military bases, private campuses or universities, hospitals that require uninterrupted, resilient and high-quality power providing backup during an outage.
They can strengthen an inadequate grid supply at an affordable cost, and utilize renewables for reduced environmental impact.
What are the critical elements of a microgrid?
As shown in the schematic on the right, a microgrid typically includes five components which are:
1. Distributed energy resources which may include wind, PV Solar, or diesel Genset
2. Energy storage systems that allow autonomous operation by compensating for the difference between power production and use.
3. A power control management system that regulates power production from each of the sources, controls power use by classifying loads and protects the battery from service extremes.
5. the optional capability to connect or disconnect from the main grid .
How do Pacific Energy's Hybrid Power Systems facilitate microgrid deployment?
Capitalizing on its hybridization diesel Genset unit architecture, Pacific Energy offers unique system solutions that provide reliable electricity in off-grid applications, or for commercial and industrial operations seeking to benefit from microgrids. AESUs pre-engineered solutions allow both generation and storage to be synchronized during peak periods and for support to grid operations. They also take full advantage of the distributed generation where power users can also be power generators (prosumers).
