MICRO-GRIDS/HYBRID POWER GENERATION and SUSTAINABLE ENERGY
What is a Micro-Grid?
There may be different definitions and descriptions of a Micro-Grid.
Typically, many definitions for a Micro-Grid include a Distributed Power solution or Resource - DER.
A classic DER, can be defined, as in the Products and Services section, as a power generation component/system (with smaller capacity than a large baseload system) that is developed for installation geographically close to the actual need and use of the power. This may include reciprocating or turbine engines as the primary mover. The DER offers reliability - always able to produce power - and is not suspectable to weather conditions. By designing the Micro-Grid to have a DER together with renewable power generation solutions and storage - allows the total system to be not only reliable but allows for integration of multiple generation solutions. A Micro-grid can act as an isolated source of power offering an efficient system for generating continuous electrical generation. It may also be designed to act as an emergency power solution when an outage or interruption of power occurs . Adding heat and cooling capabilities increases the system's efficiency and value. (This is typically done through a Combined Heat and Power component - CHP; (Co-Generation) or Tri-Generation equipment (adding a cooling component)).
Integration of different energy producing sources and assimilating them as one power source requires unique and complex controls. Monitoring each component and Controlling the System to supply the various loads required (time and magnitude) is a critical feature of the Micro-Grid.
Succinctly, a Micro-grid is a localized grouping of electricity producing sources and storage acting as a single controllable entity capable of responding and meeting various load requirements.
The Micro-Grid may be set up in conjunction with the available "macro-grid" (electrical grid) or designed to be a total isolation system from the grid. As stated above, the Micro-Grid may have sustainable or renewable energy sources, such as wind, solar, geothermal, hydro, certain types of fuel cells, etc. and include a storage system (batteries, flywheels, storage technological advances, etc.). When designed properly, a Micro-Grid can be a considered a "Green" source of energy production.
A Micro-Grid can offer:
Globex Power Group, can either lead a Team of experts to provide a turnkey Micro-Grid solution, or be a contributing provider of primary power generation (DER).
Potential Micro-Grid candidates may be business complexes, housing developments, hospitals, municipalities, university's, schools, facilities that wish to be self-reliant and isolated geographical entities (such as remote locations or island communities). Globex Power Group has assimilated global Companies and experts to produce many energy solutions for a variety of applications.
A unique component of the Micro-Grid is monitoring and controlling of all of the components and coordinating them to function as is required to meet the load demands. This can change continuously as weather parameters change. The electrical demands will also change and therefore the producing sources in the Micro-Grid must be monitored and the assimilated into the total available production so the varying demands are always met.
A Micro-Grid MAY contain:

A Micro-Grid can offer:
- Compatibility Microgrids can be 100% compatible with an existing centralized grids serving as a functional layer that builds on existing systems as an extra layer rather than competing against it.
- Flexible Due to their systematic nature, Microgrids can allow for a rapid expansion and growth pattern whether it is to add an additional producer of power, assimilate with an existing microgrid or set up a completely new microgrid. They are also able to be utilized globally in residential, commercial or in an industrial applications.
- Efficiency Due to the self-reliant nature of Microgrids, and its varied power producing components, it is generally more efficient both economically and environmentally from any single form of energy producer.

What is Hybrid Power Generation?
Hybrid Power Generation can be a variation of the Micro-Grid system described above, or simply a limited number of Generation solutions combined.
As the name implies, Hybrid Power Generation, is a combination of two or more energy producing methods. There may be multiple combinations of energy generating techniques that typically include reliable reciprocating or gas turbine components with Storage capabilities. Other power sources, such as wind and solar may be combined with energy storage systems.
At times (generally dependent on weather conditions) some renewable energy generation solutions (like wind and solar) have severe limitations. These conditions need to be analysed as potential factors that may be significant in achieving the desired goals of an application. These components may be overcome by assimilating reliable reciprocating or gas turbine power generation components into the solution.
A Hybrid Power Generation System may have multiple power generation components. At some point, a Hybrid System, with numerous power generation components, can be defined as a Micro-Grid.
It is because of this ambiguous definition, Globex Power Group defines and has designed its Hybrid Power Generation Solution as having (2) major components: a Reciprocating or Gas Turbine GenSet paired with a Battery Storage system.
Benefits of a Hybrid solution are numerous: frequency and reactive voltage support (VAR introduction), ramping control, spinning reserve, high speed regulation, reduced fuel costs, peaking power on demand, reliability, and flexible options. Also, reduced emissions, and reduced maintenance costs are associated with Hybrid Power Generation.
Globex Power Group, Inc., in a Teaming effort with other Companies in the US and additional partners in the UK and Canada, has developed (3) Standard Hybrid solutions, combining a Gas Turbine Powered GenSet with a Battery Storage System (Accommodations for other designs and options can be supplied as needed).
The "standard" systems are:
1. 20 MW System with a 5 MW Battery System - GPG HY 20 Solution
2. 30 MW System with a 7 MW Battery System - GPG HY 30 Solution
3. 50 MW System with a 10 MW Battery System - GPG HY 50 Solution

Storage
In general, storage systems have evolved and continue to evolve into viable alternatives and creditable solutions for "holding" energy produced by various generation techniques. Today, there can be many forms of storage. Major categories of energy storage include:
Due to current advances and the overall purpose of this website, Globex Power Group, will promote (2) viable, off the shelf, storage entities: A Mechanical device (Flywheel) and an Electrochemical solution (batteries).
The Flywheel, has been used for many years in mechanical and electrical systems. Today, major advancements in materials (composites) that have a higher tensile strength than steel can store more more energy for the same mass. Also, to reduce friction, flywheels may be built in vacuum chambers and have magnetic bearings.
A battery energy storage solutions (BESS) , depending on the application, are configured in one of two manners:
1. A Power Configuration or
2. An Energy Configuration
In a Power configuration, the batteries are used to inject a large amount of power in a relatively short period of time. This requires a high inverter-to-battery ratio. Applications may be to simulate a turbine ramp up for frequency regulation, spinning reverse, or black start capacity.
In an Energy configuration, the batteries are used to inject a steady amount of power for an extended amount of time. In this configuration, a low inverter-to-battery ratio is used. Applications that have power demands changing over several hours and/or shifting curtailed PV production to later in the day are examples for this use.
