基于模型预测控制的光储发电系统VSG频率控制方法 [PDF]
, 2022 随着光伏发电装机规模大幅提升，电力系统转动惯量不断降低，虚拟同步发电机（virtual synchronous generator，VSG）技术被广泛采用以应对日益严峻的电网稳定性问题。为进一步提高VSG技术对系统稳定性的改善作用，提出基于模型预测控制的VSG频率控制方法。该方法首先在同步发电机转子运动方程和逆变器下垂控制方程基础上建立VSG可优化的离散模型，再通过模型预测控制（model predictive control，MPC）预测VSG转子角频率的运动轨迹 ...

International media coverage promotes donations to a climate disaster
Disasters, Volume 47, Issue 3, Page 725-744, July 2023., 2023 The Australian bushfires in 2019–20 triggered massive amounts of charitable giving from the community. This study applied agenda‐setting theory to examine if and how disaster news coverage influenced public donations in response to the crisis. A survey of 949 Australians found that people perceived news coverage of the event to be a strong influence on

Integrative Conservation, Volume 2, Issue 2, Page 95-107, June 2023., 2023 This is a study of the spatiotemporal patterns of Human−Elephant conflict in a community area adjacent to Kuiburi National Park, southern Thailand. We examined temporal and spatial patterns of elephant crop raiding by assessing the locations of elephant raids in conjunction with environmental factors along with crop characteristics and crop ...

Secondary frequency control of islanded microgrid considering wind and solar stochastics
, 2023 As the high penetration of wind and photovoltaic distributed generation (DG) in the microgrid, the stochastic and low inertia emerge, bringing more challenges especially when the microgrid operates in isolated islands.
