Abstract
Electricity demand is increasing, as a result of increasing consumers in the electricity market. By growing smart technologies such as smart grid and smart energy management systems, customers were given a chance to actively participate in demand response programs (DRPs), and reduce their electricity bills as a result. This study overviews the DRPs and their practices, along with home energy management systems (HEMS) and load management techniques. The paper provides brief literature on HEMS technologies and challenges. The paper is organized in a way to provide some technical information about DRPs and HEMS to help the reader understand different concepts about the smart grid, and be able to compare the essential concerns about the smart grid. The article includes a brief discussion about DRPs and their importance for the future of energy management systems. It is followed by brief literature about smart grids and HEMS, and a home energy management system strategy is also discussed in detail. The literature shows that storage devices have a huge impact on the efficiency and performance of energy management system strategies.
Highlights
The demand for electricity or load variation in the power grid is changing from time to time.Meeting the demand for electricity, especially during peak hours, poses a major challenge
demand response programs (DRPs) provide a chance for customers to play an important role in the operation of power grids by curtailing or shifting their energy consumption in response to electricity price changes or other methods of financial incentives [12]
Smart dispatching among the demand and utility companies is the main application of home energy management systems (HEMS), which can help utility companies in clarifying the energy price, deploying demand response programs, and integrating more renewable and storage devices efficiently
Summary
The demand for electricity or load variation in the power grid is changing from time to time. In many countries, power grid services were regulated and operated by governmental utility companies, and private energy companies hardly owned any power systems [1]. Only the generation side participated in this deregulated energy market to sell their power to consumers and raise their profits, whereas the demand side had not any competition to reduce their consumption. This issue exposed the inflexibility of the power system [5]. The main aim of DRPs was to encourage people to reduce their consumption during peak hours through incentives offered by utility companies [7]. Demand response programs and home energy management systems (HEMS) will be discussed briefly
