Demand-Side Response Smart Grid Technique for Optimized Energy Use

Abstract

The chapter describes a dynamic smart grid concept that enables electricity end-users to be acting on controlling, shifting, or curtailing own demand to avoid peak-demand conditions according to information received about electricity market conditions over the Internet. Computer-controlled switches are used to give users the ability to control and curtail demand on a user’s premises as necessary, following a preset user’s preferences. The computerized switching provides the ability to accommodate local renewable energy sources as available. The concept offers further the ability to integrate charging electrical vehicles during off-peak periods, helping thus substantially improving the utilization of the whole electricity system. The approach is pursuing improved use of electrical energy associated with improved energy management, reduced electricity prices and reduced pollution caused by excessive use of combustion engine in transport. The technique is inherently restricted to take effect in frame of energy tariff regimes based on real-time price made to encourage and reward conscious users being proactively participating in holistic energy management strategies.

Impact of Demand Side Response on a Commercial Retail Refrigeration System

“…Currently, the minimum tender load is in the order of 10 MWs. The uptake of FFR DSR has increased significantly and can be deployed via the shedding of a single large load or via the aggregation of large numbers of smaller connected loads [4][5][6][7][8][9]. Where large numbers of loads are aggregated, multivector devices controlling a buffered thermostatic load are considered well suited for FFR DSR [10,11].…”
