On the flexibility of electricity consumers: Introducing notice time

Abstract

Abstract-Power systems with a large share of inherently intermittent energy sources require new approaches to system operation. Demand side management is seen as one potential resource for maintaining power balance in a future energy system with large amounts of volatile renewable energy generation. Existing demand response programs require flexibility in a set time frame from the electricity consumers in reaction to economic incentives. For a more detailed qualitative analysis of consumer flexibility, not only price but also notice time are imperative parameters. Former has been studied in numerous references whereas the impact of the latter has not yet been examined in depth. This paper presents a review of existing demand response programs and reflects on consumers' flexibility with respect to notice time. While some schemes include fixed notification schedules, others allow for variable notice time, or even continuous updating. In this paper, the consequences of notice time and update intervals on flexible electricity consumers are studied in Demand Bidding model with continuous forecast updates.

Enhancing market access of demand response through generation forecast updates

“…1, that Demand Bidding (DB) and Real Time Pricing (RTP) allow for flexible economic scheduling starting on the day-ahead (DA). A DR study using DB was conducted in [7]. In order to examine consumer flexibility with respect to notice time, a continuously updated Real Time Pricing (CU-RTP) approach is developed in this study.…”

“…• ability to be dispatched [3], • load management purpose based [4], • type of control architecture [5], • market level [6] • time of notification [7]. With respect to this study, the most purposeful way of classifying DR programs is to cluster them by the time when the information for providing a certain service is exchanged.…”

“…Fig. 1 shows the time frame of existing DR programs as classified in [7]. For balancing the power system, many markets such as Nordpool [10] offer energy suppliers to submit bids in consecutive markets with different time periods until the delivery hour.…”

“…Incentives can change energy habits and preferences of consumers [16,[32][33][34] and as a result, reduces energy consumption [30]. Therefore, in some countries, government and utilities (e.g.…”
