###### Abstract  
Demand-side management (DSM) is a significant component of the smart grid. DSM without sufficient generation capabilities cannot be realized; taking that concern into account, the integration of distributed energy resources (solar, wind, waste-to-energy, EV, or storage systems) has brought effective transformation and challenges to the smart grid. In this review article, it is noted that to overcome these issues, it is crucial to analyze demand-side management from the generation point of view in considering various operational constraints and objectives and identifying multiple factors that affect better planning, scheduling, and management. In this paper, gaps in the research and possible prospects are discussed briefly to provide a proper insight into the current implementation of DSM using distributed energy resources and storage. With the expectation of an increase in the adoption of various types of distributed generation, it is estimated that DSM operations can offer a valuable opportunity for customers and utility aggregators to become active participants in the scheduling, dispatch, and market-oriented trading of energy. This review of DSM will help develop better energy management strategies and reduce system uncertainties, variations, and constraints. demand-side management (DSM); distributed generations (DGs); energy management systems (EMS); renewable energy sources (RES); optimization; waste to energy (W2E) +

other sustainability elements, to some extent. Integrating multiple communication and Internet of Things (IoT) protocols in renovating conventional grid systems into intelligent grids has enabled a bidirectional information exchange [1]. This data can be utilized for a variety of energy management strategies. On the demand side, by incorporating various digital sensing and communication protocols, smart device control, and connectivity between utilities and geographically distant grid organizations, appliances can leverage this information to strategically provide an optimal strategy for better operation and efficiency characteristics. Understanding the problems related to integrating different sources and technology can provide ideas to establish synchrony between generation and load. The notion of demand-side management (DSM) is a solution to these significant challenges related to grid sustainability, security, reliability, and load profile management from the perspective of consumption and for providing strategies for load reduction. DSM is a collection of load management solutions that plan, integrate, and monitor preassigned routine operations on the basis of a consumer's consumption behavior [2]. The DSM architecture can conservatively dispatch available generation capacity, lowering emissions and peak load usage while allowing users to use their preferred energy type [3]. DSM was launched in 1970 [4] when the electrical sector offered the DSM model and architecture to manage time-of-use (ToU) and peak electricity consumption and to analyze consumer load usage profiles. DSM can establish synchrony between generation and load, taking on maximum cases of obstacles. There are substantial incentives to employ distributed generation (DG) to reduce greenhouse gas emissions, improve power system efficiency and reliability, implement competitive energy policies, and delay transmission and distribution system upgrades. DGs are made up of renewable units such as wind turbines (WTs), photovoltaics (PV), fuel cells (FCs), and biomass, as well as non-renewable units such as micro-turbines (MTs), gas engines (GEs), diesel generators (DiGs), etc. By being near the clients, DGs avoid needing a transmission system. The integration and control of DGs, storage devices, and flexible loads can form a microgrid, a low voltage distribution network that can operate in isolated or grid-connected modes [5]. Due to a lack of sufficient energy generation sources, microgrids frequently struggle to meet demand.
