This survey investigates the policy, regulatory and financial (economical and commercial) barriers, which hinder the deployment of microgrids in the European Union (EU), United States (USA) and China. In this paper, a clear view on
countries, policy tools have reinforced an existing bias toward larger centralized infrastructure rather than distributed systems, including microgrids (Levin & Thomas, 2016; Sioshansi,

The impact of state policy on the optimal design of microgrid systems, in its economic cost minimization sense, and providing an overview of the current status is assessed in Reference
This research paper presents a comprehensive review of the literature on microgrid development in the UAE, focusing on the socio-economic costs and benefits, policy frameworks, market dynamics, and environmental
In the case of microgrids, improved security, reliability, and sustainability can be marketed along with economic benefits like energy cost savings. In the case of combined
research (Liu et al. 2022) suggests a concept for a CHP microgrid that makes use of renewable energy sources. The optimum scheduling issue of the microgrid model is calculated using an

The current available literature on the impact of policy measures on the economically optimal configuration of microgrids considers microgrid sizes ranging from single buildings up to entire communities, but without explicitly controlling for the effects of microgrid size on the reported results.
Many studies exist on microgrid technologies and operation, but few studies on policies, incentives and barriers to microgrid promotion and deployment. It is to be understood that microgrid policies are unavoidably related to distributed energy polices and precisely renewable energy.
The reviewed papers show that economic incentives can certainly have an impact on the economic optimal microgrid configuration: Zachar et al. investigate the impact of both a 30% and a 50% tax credit towards renewable energy investments.
To overcome the financial problems, many researchers have prepared various types of microgrids that generate electricity from various types of flow resources, like hydro, solar, biogas, and air current power stations, whose system is called a compound flow power system.
Support for microgrids comes from research and development (R&D) programs at federal and state levels, software and tools, grants and funding support to incentivize demonstration projects, and tax and financial incentives for the installation of distributed energy [2, 3, 6, 126].
