  • Chapter

Demand-side Flexibility in Smart Grid

Part of the book series: SpringerBriefs in Applied Sciences and Technology ((BRIEFSAPPLSCIENCES))

Abstract

Maintaining the balance between load and supply is one of the main challenges of the power system operation.This balance is perturbed by three types of events in different time frames: rapid random fluctuations, and slow periodical fluctuations and rare abrupt instantaneous changes. The variable production of RES combined with fluctuations from the demand side results in a net-load profile with high volatility. Flexibility is the ability capability of the system to accommodate variation in net-load, by modulating the feed-in or feed-out of power across the grid over time to withstand variations originated from both generation and demand-sides. This chapter discusses the general concept of flexibility in the power system, main sources of flexibility and signs of inflexibility.
