Natural coastlines are vital for ecological security and sustainable development. To mitigate their decline, China has implemented requisition-compensation balance policy (RCBP) for coastlines, adapted from the management of cultivated land. This study systematically reviews the policy’s institutional evolution and highlights fundamental distinctions between coastlines and cultivated land in functional services, spatial hetero...

The inherent randomness and intermittency of offshore renewable energy sources, such as wind and solar power, pose significant challenges to the stable and secure operation of the power grid. These fluctuations directly affect the performance of grid-connected systems, particularly in terms of harmonic distortion and load response. This paper addresses these challenges by proposing a novel harmonic control strategy and load re...
