Smart Micro-Grids & Heat Networks
What are Smart Micro Grids?
A Smart Micro Grid is a scaled down version of the traditional centralized grid that distributes energy for the the main power grids. However a Micro Grid differs from the main grid by generating, storing and distributing locally generated electricity and heat. In many case the buildings have embedded renewable energy generation and storage. They are usually owned and operated by individual organizations or communities. Smart Grids operate as either: Stand alone, Island mode or Grid coupled.
Smart Micro Grids are managed by Artificial intelligence via The Internet of Things (IOT)
Low cost, locally generated, renewable energy
Legislative changes, global warming, and advances in technology and communications, will change the way we generate, distribute and consume electricity.
The traditional model of large thermal fossil fuel and nuclear power stations will be replaced by the Internet of Energy: A highly connected system of responsive power generation from both suppliers and consumers resulting in clean, secure and reliable electricity to power the homes, businesses and vehicles of tomorrow.
Home owners, Housing Associations and Landlords have the opportunity to benefit from significant energy cost savings through community embedded energy generation, storage and distribution schemes that deliver independence from the lager energy companies.
Business users have the opportunity to make significant cost savings through embedded energy generation, storage and utilization. To power sites during peak charging periods without incurring peak tariff costs and disruption to production patterns.
Sufficient battery storage will also negate the need for other forms of back up generation to provide on site UPS. When the buildings are not occupied or generating surplus energy at weekend or during summer shut downs they will have the opportunity to sell surplus energy to local homeowner’s or businesses who need the energy. Those close to a hospital or community center may chose to donate some free spare energy.
Fuel cells generate electricity through harnessing the chemical reaction of positively charged hydrogen ions with oxygen. In order to sustain the chemical reaction fuel cells require a continuous source of fuel and oxygen. As fuel cells are powered by hydrogen and oxygen they generate electricity with very little pollution, as the by-product of combining these elements is water.
With the UK government announcing a ban on the sale of new diesel and petrol cars by 2040, Electric Vehicles (EV) mass adoption will be inevitable. This requires vehicle-charging systems that can charge rapidly and are readily available. Energyst are able to advise on the selection and deployment of suitable EV charging stations that are powered through green renewable energy.
The smart city concept visualizes how cities of the future will incorporate technological developments into a smart social infrastructure. Smart living allows greater connectivity and local energy management to create environmentally sustainable urban development.
Solar PV is able to provide scalable ,clean energy from small scale household installations to grid scale projects. Allied with an effective storage medium, energy generated by solar PV throughout the day can be stored for discharge during the evening periods of peak demand.
The UK has the best onshore natural wind resource in Europe. Wind projects can be scaled from individual turbines providing power for individual homes and small businesses to industrial sites and whole communities.
Energyst advise on the integrated energy management for micro-grid and heat network solutions, with smart grid optimization for smart cities. This technology enables renewable energy generated from sources such as wind, solar, hydro and geothermal to be stored locally and ultimately utilized more efficiently.
By design, ultimate flexibility is available for business, communities, electricity grid and heat network operators to evolve from the traditional model of separate electricity and heat provision to a future smart system of integrated supply and consumption. Lower energy costs, greater security of supply creating a natural transition to a low carbon economy.
Battery storage will increasingly provide balancing services to local and national electricity networks, alleviating imbalances in supply and demand and allowing for greater penetration of intermittent renewable energy generation on to the grid.
Mini Grid A mini-grid is an off-grid electricity distribution network involving small-scale electricity generation. Often conflated with microgrids, a mini-grid is sometimes defined as having a power rating less than 11kW and as being disconnected from utility-scale grids. The United Nations Framework Convention on Climate Change (UNFCCC) defines a mini-grid with a power rating below 15MW and disconnected from larger electric grids. A universal definition for a mini-grid remains to be solidified, but the term is often utilized as a cost-effective solution for electrifying rural communities where a grid connection is challenging in terms of transmission and cost for the end user population density.[3 Source: Wikipedia
