An effective demand response (DR) model framework for DR management systems in a residential premise is proposed. The proposed model consists of dynamic price signals from load serving entity (LSE), benefit function, and loss of consumer comfort. The conventional approaches generally consider these factors as independent in their formulation. Since these factors have functional relationship, the proposed model points to a holistic approach to capture the relationship. The scheduling model can be integrated with the home energy scheduler coupled to the smart meter, which facilitates the flow of dynamic price and energy consumption information to and from the household premise. The objective is to maximize net consumer surplus, which is formulated as a function of all aforementioned factors. A method for developing a practical and dynamic consumer benefit model for matured DR programs is proposed in this paper. For the purpose of showing the effectiveness of dynamic benefit function, a set of analytically formulated benefit functions is also considered. The suitability of the dynamic benefit function, as compared with other alternatives, is illustrated with an example. This paper also reports the dynamic price design from the view point of LSE, in order to cover the risks of wholesale price volatility.

SmartGrids were introduced to make the grid operation smarter and intelligent. SmartGrid operations, upon appropriate deployment can open up new avenues and opportunities with significant financial implications. SmartGrids can continue towards enhancement of power market. The current status of the power market as well as initiations of SmartGrids in India are studied to scrutinize the potential power market enhancement with the advent of SmartGrids. This paper presents various SmartGrid initiatives and implications in the context of power market evolution in India.

India is struggling to meet the electric power demands of a fast expanding economy. Restructuring of the power industry has only increased several challenges for the power system engineers. A major chunk of the power losses is a direct derivative of the poor management of distribution networks. Distribution automation (DA) has been aimed at reducing losses, and improving reliability and financial viability of state utilities. Firstly, this paper presents various benefits achieved by major Indian utilities in transitioning towards automation. Enroute to the proposed vision of introducing viable Smart Grids (SG) at various levels in the Indian power systems, it is recommended that an advanced automation mechanism needs to be adapted. This is then projected to be feasible through invariable dependance on several open standards, whose integration for interoperability, flexibility, scalability, modularity and vendor neutrality is deemed pivotal. Various examples of existing structures of automation inIndia are employed to underscore some of the views presented in this paper. Finally, a potential SG architecture for Indian power systems is proposed with a discussion on its implications.
