Abstract

The growing need to reduce greenhouse gas emissions, and the emergence of a competitive electricity market all over the world, calls for optimal deployment of the existing generation facilities coupled with limiting the dependence on fossil fuels for electricity generation. Renewable energy resources provide a greener option for electricity generation. However, owing to their intermittency and stochasticity, the grid integration of these resources poses serious operational issues. The increased share of renewables in the generation mix augments net uncertainty and makes it more challenging to maintain supply-demand balance. One of the solutions to mitigate the variability of renewables is incorporating energy storage means. However, installing energy storage devices of suitable size is often associated with large capital costs. In this regard, Demand-Side Management (DSM) options can provide an efficient and cost-effective solution. DSM is the concept that focuses on enhancing the efficiency of various energy processes and also provides options for better utilizing the available generating facilities by adjusting load demand. This chapter provides a detailed introduction to the DSM. The detailed modelling of battery energy storage devices, DR models ...
