Smart grid

Electric Grid is today hailed as the world’s greatest engineering network - comprising of large generation plants, which yield electricity and subsequently transferred on HV Transmission lines and eventually distributed to the millions of consumers. For over a century, the role of the Grid has been in taking the power from the limited generation plants and supplying to the millions. There has also been integration and synchronisation between the central grid and the state grids. However, in the recent past, there has been a drastic shift in the dynamics of power generation and consumption. This shift has been ushered by De-centralised Generation, more commonly known as Distributed Generation.

This can be ascertained from the below facts:

  1. The generation of power has now started to begin at the distribution side. This has changed the traditional roles of generation, distribution and transmission and the consumers are now turning into “prosumers”, because electricity flow is no longer one-directional; but, it has now become two-way phenomenon.

  2. Transmission, with its heavy T&D losses, is facing a tough challenge from Energy Storage Systems. “Distributed Generation + Storage + Distribution” has fewer network losses in comparison to the traditional “Generation+Transmission+Distribution”

  3. Digitization has changed the load demand - earlier, Inductive loads had greater numbers and consumed the highest power. Today, digital devices control the grid and they require quality power and stable voltage and they can forecast voltage and current on hourly basis.

  4. Electricity regulatory Bodies have started controlling the demand- response through Price and tariffs are accordingly being revised for different categories of consumers.

  5. The dispatch centres are emphasising on energy efficient and environmentally friendly dispatch of energy rather than on Merit Order dispatch.

  6. Greater Integration of Solar rooftops, Solar + Wind Hybrid models, and Electric Vehicles in to the grid shall fulfil the demand for power on short terms, increasing the complexity and dynamics.

Utilties are seeking data on understand the load behaviour pattern and the smart grid, equipped with sensors, is making that possible. The smart grid shall oversee the power being consumed inside every house and the grid shall be something like an internet connecting everything.

With greater solar rooftops coming up, the utilities need to calculate the energy input, energy balance (through net-metering) from these distributed generation sources, and the System Operators are now calculating the capacity for the next day for every customer premise which are having the Solar rooftop and then scheduling the dispatch. These developments shall change the traditional roles of generation, transmission and distribution companies.Time-of-Day monitoring shall ensure that customers are charged during the peak demand hours.

Smart grid is an electricity grid with communication, automation and IT systems that enable real time monitoring and control of bi-directional power flows and information flows from points of generation to points of consumption at the appliances level.

Smart grid allows consumers to choose their source of energy and monitor their usage of energy.

The Key components of Smart grid are :

1. Advanced Metering Infrastructure
2. Peak Load and Power Quality management
3. Transformer Monitoring systems
4. Mobile Crew management Systems
5. Enterprise IT Systems
6. Energy Storage
7. Electric Vehicles
8. Common Command Control Rooms
9. Cyber Security

Smart grid Test equipments are automated systems that can test all kinds of relays from any manufacturer. Modern automated test instruments take away human error and also reduce the amount of work.

Syselec Technologies supplies equipment to utilities who seek Smart Grid solutions for better control and monitoring.
