“…The central government should clarify the policy objectives of the "river chief system" when it is introduced in Yantai, including the assessment criteria for both economic and environmental aspects, and include the assessment results in the performance indicators of officials and implement open government affairs, which is conducive to the government Internal, public and superior assessment of river pollution control. In order to ensure the scientific nature of the assessment results, Yantai City should develop differentiated assessment indicators according to local conditions, adopt different assessment standards for rivers and lakes with different pollution conditions and ecological environments, and adopt different assessment standards for "river chiefs" in different areas to avoid a "one-size-fits-all " [13].…”

In response to his call for environmental governance, and in order to build a clean and beautiful home, government agencies have been committed to finding effective policies and measures to control river water pollution, and the "river chief system" came into being. However, the "River chief system" is not smooth in the implementation of the policy. As a self-created governance policy of Wuxi, it inevitably has local characteristics. And whether a policy applicable in Wuxi can also achieve good results in Yantai? Based on the research method of questionnaire, this paper explores the effectiveness and shortcomings of the implementation of the "river chief system" in Yantai City, and puts forward suggestions to improve the "river chief system" or measures to solve the problem of river pollution, so as to make the "river chief system" more dynamic and vital in Yantai and achieve actual results.

“…Yu Huayang and others studied the energy conversion device of solar and wind power generators, which marked that the research on wind-solar power generation systems entered the stage of practical application. To solve the structural defects of the conventional wind-solar hybrid power generation system, Wei et al [8] proposed a compact spherical wind-solar hybrid power generation system (CSWS-HPS) and achieved a considerable power generation efficiency. To improve the reliability and energy utilization of renewable energy generation systems, Liu et al [9] investigated the optimal control method of wind-solar hybrid devices designed using the power prediction method and proposed an MPPT optimal control strategy.…”

To address the severity of the wind and light abandonment problem and the economics of hydrogen energy production and operation, this paper explores the problem of multi-cycle resource allocation optimization of hydrogen storage systems for coal–wind–solar power generation. In view of the seriousness of the problem of abandoning wind and photovoltaic power and the economy of hydrogen production and operation, the node selection and scale setting issues for hydrogen production and storage, as well as decision-making problems such as the capacity of new transmission lines and new pipelines and route planning, are studied. This research takes the satisfaction of energy supply as the basic constraint and constructs a multi-cycle resource allocation optimization model for an integrated energy system, aiming to achieve the maximum benefit of the whole system. Using data from Inner Mongolia, where wind abandonment and power limitation are severe, and Beijing and Shanxi provinces, where hydrogen demand is high, this paper analyzes the benefits of the hydrogen storage system for coal–wind–solar power generation, and explores the impact of national subsidy policies and technological advances on system economics.

Renewable sources such as solar and wind is the ideal solution for sustainable development. However, protection methods for renewable energy penetrated power systems still faces a lot of challenges. We claim that the performance of the differential protection is highly related to the model accuracy. Using a detailed distributed parameter line model, this paper developed a novel differential protection method for renewable energy penetrated power systems based on traveling waves with high rapidity and reliability. The optimal differential point is also discussed to enhance protection rapidity. Experiments demonstrate that the proposed protection could soon detect internal faults with high fault resistance while maintaining reliability when external faults occur.
