Green and sustainable power is the need of the day. With widening supply and demand gap, power management has become one of the most critical areas of concern all over the world. India’s energy consumption is increasing at one of the fastest rates in the world. Hence, we require Substation Automation Systems in the present day substations to efficiently control and deliver power. The main objec...

Restructuring of electric industry has seriously affected the operation and planning process of electric power systems. Due to the unbundling process and new market requirements, a set of new challenges and goals have been introduced in the field of transmission planning. Moreover, the uncertainty level of input data to planning process has been increased significantly. In this paper first, the...

in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...

Substation refurbishment planning was traditionally initiated by deteriorated network performance indices and the physical observed state of the network. However, it can also be too late, resulting in deteriorated customer service and unnecessary company risk. A Plant Health Index is developed, to understand and assess the condition of equipment during its life cycle. The plant health index wil...

A new market based approach for transmission expansion planning in deregulated environments is presented in this paper. In this approach, transmission-planning decisions are made based on the electric power market conditions. The main contribution of this research is 1) Introducing a new probabilistic tool for analyzing the electric market conditions, 2) Defining new criteria for ranking transm...

IEC61850 communication standard for digital substation automation creates a new way to think about conventional protection scheme and configuration of substation. The presence of communication link in process bus makes a revolutionary change for future digital substation. This paper discusses briefly about process bus architecture and presents a new approach of thinking in busbar structure to m...

500kV substation is especially important to the grid of our country, once it encounters lightning damage, the safety and reliability of the whole power system will be directly affected. As lightning intruding waves will cause overvoltage on electric equipments by intruding from the transmission line or straightly stroking the substation, which seriously influences the insulation level of equipm...
