lntelligent Power Grid Platforms xGrids
First-Ever Intelligent Power Grid Management Solution For Power Utility Companies
Background
- The Electricity industry has been similar during last 150 years since it was utilized as the energy source.
- Electricity flowed in one direction from power plants to consumers. (actors: suppliers and consumers)
- So, it was not such a hard job to manage the power grid.
- There have been a few management systems for each grid area during since 1990s.
- EMS for power plants, SCADA for transmission line and DMS for distribution line.
- The power grid goes more and more complicated with solar panels, wind turbines and electric vehicles, etc.
- The electricity is going to flow in any way and it is very challenging to manage the security, cost, loss of a whole power gird. (actors: suppliers, consumers, prosumers)
2019 Advanced EMS Forum in US
- World is moving forwards renewable energy
IEC TC57 Communication Standards Architecture
- Even if there are international standards for communication between systems
Case of KEPCO in 2013
- Legacy grid management systems can not connect to one another easily (No Utility-Scale Solution)
- So, the utility-scale smart grid solution is strongly needed to transform a traditional power grid to an intelligent one.

- Benefits From xGrids SCADA (2/2)
- xGrids is KEPCO's flexible power grid management platforms which comprises three sub platforms, which are platform of power grid analysis, platform of power systems integration and platform of intelligent application developments.
- xGrids made a power grid as a service coming up with a lot of benefits in electricity quality, cost reduction and many more perspectives.
- There are over 2,000 power utility companies in the world and they are challenging in implementing smart grid by applying ICT technologies to the traditional power grid since 2000s. The objectives of smart grid is enhancing efficiency in quality and cost as a whole grid perspective. But, the solutions in the market are only for certain purpose and cover partial area of the grid.
- Utility companies need smart grid platforms for integrating all the legacy solutions, data and developing intelligent apps. xGrids is a first-ever proven, utility-scale, innovative platforms for implementing a real smart grid bearing efficiency.
- KEPCO is one of the biggest power utility company in the planet with millions of facilities, lots of grid management systems such as SCADA, DAS, Renewables, etc. and 22 millions of customers. The systems were not able to connect to one another with being lack of interoperability. The quantity of data has been tremendous. But, there was no utility-scale smart grid solution in the market.
- Therefore, KEPCO researched to develop a flexible smart grid plaforms comprising integration platform, analysis platform and intelligent apps platform supporting standards and proprietary techs for the first time in the world during 2013-2016.
- xGrids is a game changer in the implementation of utility-scale smart grid as there has not been a solution for a whole-grid perspective. There are grid management solutions for specific purpose such as SCADA, DMS, RMS etc in the market. It was very challenging to develop a flexible smart grid platform for any utility company. xGrids can transform any traditional utility company into smart grid with three platforms structures.
- KEPCO became a smart energy creator after deploying xGrids and reduced the yearly per-household power outage time from 10.88 mins in 2015 to 8.59 mins in 2018, which is world No.1.
- Thanks to xGrids, KEPCO became world No.1 utility company in Forbes rankings and won the CIO100 Awards in 2016. xGrids was introduced twice from 2017 to 2018 SCADA World Summit in London and Singapore.
- In addition, KEPCO reduced next SCADA cost from 90.5million USD to 39.6 million USD on the basis of xGrids and enhanced its grid systems availability from 99.9% to 99.9999%. KEPCO has developed 16 intelligent applications on the xGrids during 2014-2019 coming up with a lot of business benefits. KEPCO is currently trying to analyze and reduce the congestion cost of about 5 billion USD.
- xGrids has created a utility-scale smart grid platform solution which has not existed in the industry. xGrids is a huge breakthrough innovation to go forward from traditional power grid to smart grid coming up with reduction of electricity loss and cost, improvement of power quality and many more values. It is a Smart Grid as a Service making electricity industry more intelligent. xGrids has been deployed to KEPCO (Korea Electric Power Corporation) which is within the 5 biggest companies in the world and proven the benefits expected by smart grid. xGrids can boost power utility company to the 4th industrial revolution era.
