“…Various studies distinguished between different categories of DR strategies related to electricity systems. The most usual classification of DR strategies related to the electricity system is based on motivators for the customers: (1) price-based motivator and (2) incentivebased motivator [140][141][142][143]. The incentive-based DR were described differently in the various studies.…”

The highly varying character of district heating (DH) demand results in low capacity utilization of the DH plants, as well as increased use of fossil fuels during peak demand. The aim of this study is to present an overview and a comprehensive classification of measures intended to manage these load variations. A systematic literature review was conducted based on previously defined search strings as well as inclusion and exclusion criteria. Two scientific databases were used as data sources. Based on 96 detected publications, the measures were categorized as (1) complementing DH production in heat-only boilers (HOBs), or geothermal or booster heat pumps (HPs) (usually controlled by the DH company), (2) thermal energy (TE) storage in storage units or in the network (controlled by the company), and (3) demand side measures, which can be strategic demand increase, direct demand response (DR), or indirect DR. While the company has control over direct DR (e.g., thermal storage in the thermal mass of the buildings), indirect DR is based on communication between the customer and the company, where the customer has complete control. The multi-disciplinary nature of this topic requires an interdisciplinary approach.

“…For incentive-based DR programs, users behave individual or collectively to reduce their consumption during a certain amount of time in terms of the requirements of the operator or economic transactions that are agreed upon in a market. In these programs, users enter bidding processes by demand reduction as proposed by [40] In most cases, the government must promote the initial stages of these programs [41], the incentives and their permanent restructuration according to the types of users, their power levels and the participation times [42] which will be reflected in changes on the demand curve [43]. Therefore, the coordination of the load disconnection is carried out through an integrator agent supported on optimization algorithms set to reduce load peaks [44].…”

This paper provides a review and analysis of trends related to demand response (DR). The authors have considered six different topics for the analysis of DR trends: Users, Network Services, Markets, Complementary Programs and Distributed Energy Resources (DER). A brief summary of the consulted articles is included and the behavior of the different DR trend-related topics is shown up to the year 2017 and their projections for 2020. As a result, the characterization of the main DR topics is obtained as well as its current and future trends. Based on the results of the study, it is concluded that the topic of complementary programs is a trendsetter for current trends and it is expected that there is a future change of focus towards the users and new services.

“…On the demand side, the demand response (DR) methods can effectively improve frequency stability by controlling loads. Typically, DR can be categorized into two basic categorizes-price-based demand response (PBDR) and incentive-based demand response (IBDR) [9][10][11][12][13][14]. PBDR offers the time-varying electricity rate while IBDR offers the incentive payments or rate discount to DR participants; in exchange, DR participants agree to provide contract-based load-reduction or load-shedding services.…”

This work develops an underfrequency preventive control strategy for an islanded power system with a high penetration of wind power generation. First, the preventive control strategy uses the frequency nadir forecasting module to analyze the frequency stability under largest diesel generator tripping (N-1) contingency events. If predicted frequency nadir is too low, four frequency support methods are then analyzed and used for preventing potential frequency stability problem. They include generator rescheduling (GR), the use of battery energy storage system (BESS), direct load control (DLC) and emergency demand response program (EDRP). In terms of the GR method, the optimal diesel generator dispatch is obtained, with sufficient frequency stability and minimal fuel cost and start-up cost. In the BESS method, the optimal instantaneous power output from BESS is obtained based on its frequency support capability. With the DLC or EDRP method, the optimal contract-based load-shedding or the load-reduction to provide frequency support is obtained, respectively. Then, the operating costs of each method to support frequency are analyzed. The research methods and simulation results are very useful to the low-frequency protection of actual power systems with high renewable power generation. This work proposed a complete defense strategy in a microgrid system. It combines GR, BESS, DLC and EDRP. Therefore, the system operators have many options to implement their defense strategies, based on the operating costs of various methods. In other words, the proposed defense strategy provides a more flexible solution for the protection of micro grids with a high renewable power penetration. Therefore, the solution considers the system safety and economical aspects.
