Sh. N. Nallarasan has been the Deputy General Manager of Power System Operation Corporation Limited (A Government of India Enterprise) since August 2012. He served System Operation at various regional load despatch centres (RLDCs) as well as national load despatch centre (NLDC) at Power System Operation Corporation Limited (POSOCO) and has more than 30 years of wide experience in power sector. He has experience of managing power system operation under changing scenario and upgraded technological environment. He started his illustrious career when he joined Central Electricity Authority (CEA) through Central Power Engineering Services. He has worked extensively in synchronisation of state grids to regional grids and was instrumental in formation of integrated national grid of India. He has specialization in Power System Operation, Planning, Demand forecasting, Restoration and handling load generation balance. Other areas of expertise of Mr. Nallarasan include Electricity Markets including Power Exchanges, Open Access in Inter-State Transmission System, and Regulatory affairs besides expertise in Load Despatch Technology. He has worked closely on implementation of Reserve Regulation Ancillary Services (RRAS) and pilot project phase of Automatic Generation Control (AGC). Prior to joining PowerGrid Corporation of India Ltd. in January 1995, he worked in the CEA. He Post-graduated with a Master of Engineering Degree in Electrical Engineering from the College of Engineering, Guindy, Anna University, Chennai.

The evolving complexity of the modern power system over the century necessitated the invention of set of analytical tools to help design and analyze the power system. As a result, sophisticate class of power flow analysis tools, transient stability analysis tools and electro-magnetic transient analysis tools being used today have evolved. Present day power system is being called the smart grid, cyber-physical power system and micro-grid. They consist of distributed renewable energy sources in addition to the bulk sources. This increased sophistication, speed and wider reach of controls, and complexity of the primary system and its controllers have necessitated the evolution of a modern test environment, popularly called real-time digital simulator. The same advances in digital technology which have enabled the sophistication of the system control devices have enabled the design of real-time digital power system simulators. This presentation briefly discusses the conventional applications of three independent tools – one in each class, a hybrid-simulator and then share the vision of a future simulation environment.
