Demand Side Management, an integral feature of smart grid, exhibits high potential in load balancing and load shifting for efficient management of the power grids. Strategically designed DSM mechanisms can help mitigate load shedding and facilitate peak load management of grids. In India, only flat rate and inclining block rate tariff mechanism exist for residential customers. With the onset of 14 smart grid pilot projects in India, there is a need to address the realization of potential underlying various features of a smart grid. As India is a price sensitive market, time of use tariffs and other demand response programs are expected to potentially affect the consumer behavior in power consumption. In this paper, the usage pattern of residential customers, collected from a pilot project in India is analyzed for scaling the potential of DSM strategies. Simulations have been carried out for a price based mechanism as well as an incentive based mechanism to evaluate the underlying potential of DSM exclusively for residential consumers. The results of the simulation indicate that there is a definite scope for load balancing as well as financial savings. [ABSTRACT FROM AUTHOR]

The rapid growth of air conditioners (ACs) in developing regions exacerbates some of the issues present in their electricity systems. Direct Load Control strategies can manage peak loads for optimizing energy usage for users and utilities. When applied to air conditioning, these strategies can be used for Demand Side Management which has not been fully explored for developing regions. In this paper a novel Direct Load Control mechanism is proposed, wherein control is based on technical constraints (generation capacity). To determine the effects of the proposed mechanism, a case study of the Indian State of Karnataka is carried out. The results indicate 0.88% energy savings and a reduction of almost 2% in regional peak loads in a state where only around 5% of all households have AC units. The case study shows that an AC Direct Load Control can have significant economic and environmental impacts, and can help improve current energy, water and climate issues. Continuous improvements in both energy access and economic conditions of developing regions are leading to a larger number of AC's installed, meaning that a mechanism that enables sustainable AC consumption could be of great use for all the stakeholders in the developing countries' electricity sectors. • A novel Direct Load Control for residential air conditioning is proposed. • The control can be implemented in developing regions without price-based markets. • A case study of the novel control shows a summer demand reduction of 0.88%. • The reduction of the demand leads to environmental and economic benefits. • The proposed control reduces negative impacts of growing air conditioning demand.

In India, power shortage is a major issue for economical growth. According to the data provided by National Load Despatch Centre, peak power shortage in Tamilnadu during the year 2014 varies between 3000 MW and 4000 MW. This power shortage can be reduced by increasing installed capacity of conventional and non-conventional energy sources. But the construction of new generation plants is cost-effective and also power generation is not assured throughout the year. This power shortage can also be minimized by implementing load management in the consumer side. This paper focuses on the reduction of peak demand by the proper operating schedule of major equipments. For this analysis, three rice industries have been considered. The major operating sections in the rice industries are pre-cleaning, soaking, pre-milling and milling. In this proposed work, to reduce the peak demand, the operating time of pre-milling section is rescheduled using the optimization techniques, DE (Differential Evolution), PSO (Particle Swarm Optimization) and ABC (Artificial Bee Colony). The rescheduled results given by DE, PSO and ABC algorithms reduce the peak demand cost of the energy consumed in three rice industries. However, the optimum scheduling obtained by ABC reduces the feeder power flow than the DE and PSO scheduling. [ABSTRACT FROM AUTHOR]

Abstract: The paper introduces the approach and concept for DSM in India. A comprehensive methodology for implementing a DSM programme in India has been outlined. Detailed step wise action plan formulated for planning and implementing of DSM programme in India is presented. Various policies and regulations framed by India for promotion of DSM activities targeting different sectors are studied. The deficiencies in the existing regulatory and policy framework which have withheld deployment of DSM programmes on a large scale in India have been identified. A number of barriers and challenges that are needed to overcome for realizing the potential of DSM in India are also discussed. [Copyright &y& Elsevier]

Abstract: This paper presents the results of the application of model (developed in part I) and simulation algorithm (developed in part II) for determining the techno-economics of battery storage type hybrid energy system intended to supply the load of a rural remote area having a cluster of nine villages (grid isolated). The hour-by-hour simulation model is intended to simulate a typical one month period of system operation. For simulation purpose, hourly solar insolation data and load data have been generated and used as an input data. Demand side management (DSM) is used in this study to smooth out the daily peaks and fill valleys in the load curve to make the most efficient use of energy sources. The economic analysis has resulted in the calculation of optimized hourly, daily, and monthly system unit cost of proposed hybrid energy system. The obtained results represent also a helpful reference for energy planners in Uttarakhand state and justify the consideration of hybrid energy systems more seriously. [ABSTRACT FROM AUTHOR]

• Voltage profile improvement in distribution network using Demand Side Management. • Cost and load shedding optimization. • Real and reactive power support from consumer batteries. • Analysis with realistic loading conditions under frequency linked pricing environment. Voltage stability improvement and load profile management remain the major concerns of the power system load serving entities. The evolution in demand side management technology with automatic control enables a large number of appliances including energy storage devices to provide efficient ancillary services for the distribution utilities. In this paper, a novel methodology is developed for residential consumers using battery energy storage systems as a key vehicle for centralized incentive based demand side management. The aim is to employ energy storage at end-users' premises to provide both active and reactive power support to the distribution utility so as to achieve the desired voltage stability margin at various network nodes while optimizing the deviation settlement charges under frequency linked pricing environment. The results indicate that the centrally controlled active and reactive power dispatch from the energy storage minimizes the load shedding required to bring the network node voltages within the operating limits and optimizes the costs involved. The demonstration is carried out on the IEEE-33 bus radial distribution system using the realistic loading data of a distribution utility in India. The proposed strategy could be of immense importance to the distribution utilities to optimize load curtailment and maximize their social welfare while operating under real time pricing environment.
