Energy is the foundation of national economic and social development. With the rapid development of the global economy, energy shortage has become an urgent problem for countries to solve, and it has gradually become a bottleneck restricting Chinese current and future development. The ecological environment pollution is caused by the development and utilization of traditional energy. The problem is getting worse. How to develop and utilize clean energy while improving the environment and reducing pollution has become one of the important issues that countries need to solve urgently. Biomass energy (referred to as biomass energy) is widely distributed, renewable, and easy-to-use green energy, and its effective development and utilization is of great strategic significance for driving the development of emerging energy industries, preventing global warming, and promoting the establishment of a circular society. Therefore, it is of great scientific, economic, and social significance to develop and utilize biomass energy efficiently, relieve the pressure of energy demand, improve the environment of the ecosystem, and ensure regional economic development. For this reason, this paper designs energy complementation and bidirectional coupling between gas-electric systems, highly nonlinear operation characteristics of gas network components, gas network pipeline leakage failure modes, and multiple failure modes of compressor stations and carries out probabilistic risk assessment of gas-electricity integrated energy system.
PPP model is expected to solve the difficulty of finance in city village reconstruction. The risk of PPP project during its implementation becomes the key question of common concern for all the participants. There are more risks than common projects in PPP projects. The risk will be particularly analysed and the tactics of risk allocation will be effectively brought forward in the city village reconstruction PPP project to put forward an ecosystem evaluation index system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
