“…Load shifting assumes the presence of regulated loads and is regarded as an excellent approach for preserving total energy balance as well as user comfort and well-being when each load is cut off and restored at a later time. Strategic conservation reduces overall seasonal energy consumption, mostly by eliminating wasted energy, and so improves system efficiency [45]. On the other hand, strategic load growth leads to an overall increase of seasonal energy consumption [45].…”

The high rate of penetration of renewable energy sources leads to challenges in planning and controlling the production, transmission and distribution of energy. A possible solution lies within the change from traditional supply side management to demand side management. Buildings are good candidates for implementing a demand response model since they account for around 39% of global final energy use and are stably connected to all infrastructure networks. As a result, employing buildings as "players" in energy networks is considered now more than ever compelling. Recently, significant improvement has been denoted in the thermal efficiency of the building shell and the energy efficiency of the HVAC systems in new and renovated buildings. However, despite the reduction in energy demand regarding the space conditioning, buildings continue to be passive end users of the energy system. In order to ensure that they are capable of providing the necessary energy flexibility to balance intermittent energy production, a first step is to establish a formal, standard, and robust method of characterizing the energy flexibility provided on the demand side. Buildings can supply flexibility in a variety of ways, but there is currently no fixed and consistent method for quantifying the amount of flexibility a building can provide to future energy systems. In this paper, an overview of the literature on building energy flexibility will be offered, as well as an introduction to the concept of building energy flexibility and the methodologies used to define and evaluate it.

“…According to the previous challenges, utility companies are forced to treat these problems by different methods . To dissolve the previous challenges there are many common alternates such as distributed generation (DG), storage systems, capacitor banks (CB), load reduction, and demand-side management (DSM) [6,7,8]. DG, CB, and storage systems are the most expensive technologies and may not be suitable to match available generation with demand in some cases, while load shedding or load curtailment is indispensable to prevent any network overloading.…”

“…Furthermore, Peak clipping, flexible load shape, and valley filling are used to reduce peak and fill the offpeak demands, respectively [10,15]. Numerous articles on the DSM of Smart Grids (SG) have been published; these studies mostly address distributed generation with integration of renewable energy, demand response (DR) load scheduling that is optimum, and innovative enabling technologies and systems [4,7,11,16]. Also, Numerous articles on the DSM of Smart Grids (SG) have been published; these studies mostly address the available optimization approaches for applying DSM [8,9,19].…”

In the last decade, there has been a great interest in applying Demand Side Management (DSM) actions in electric power systems as an alternative to constructing and operating new capacity generation units. Also, DSM allows customers to make decisions that affect their energy consumption, which reduces peak-hour energy providers' demand and reshapes the load profile. This paper proposes a methodology for applying load reduction results from DSM techniques to electric power networks. This methodology uses sensitivity analysis to select the buses on which the load reduction will be performed. Furthermore, changes in hourly system loading are considered, and the impacts of these variations on the system's performance are analyzed. Also, the Monte Carlo Simulation (MCS) methodology has been utilized to consider the load uncertainties. The DSM has been effectively validated on two power distribution networks. The first is the IEEE 33 standard system, while the second is a practical distribution network, which is Shebin El Kom feeder-Menoufia Governorate South Delta Electricity Company. Different indicators are used to assess the enhancement of the network's performance. Simulation results concluded that applying DSM techniques reduced the power taken from the substation, reduced the active power losses, and improved the minimum voltage with the daily loading variation as well as at peak loading.
