Transient Modelling of Hydropower Plants

, 2016
Any changes of the volume flow through a turbine gives acceleration or deceleration of the masses of water in the penstock. This induces dynamic pressure changes in front of the turbine. A pressure transient must be controlled as it can cause severe damage on mechanical equipment, such as a turbine, if it becomes too abrupt.

Preliminary Study on Unit Commitment for Renewable Energy Integration Considering Operation Cost and Life Cycle Assessment

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Most countries, including Japan, are focused on achieving net‐zero greenhouse gas (GHG) emissions by 2050, which requires quick action. Despite the increasing level of renewable power generation in power grids, fossil fuel power plants still have a significant role in producing GHG emissions, causing serious environmental issues.

Multi‐Strategy Synergy‐Based Differential Evolution for Large Wind Farm Layout Optimization

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Exploring clean energy alternatives to fossil fuels has become a major research focus worldwide. Wind energy is regarded as one of the most promising renewable energy sources due to its clean and sustainable nature. However, wake interactions among turbines significantly reduce power conversion efficiency, making wind farm layout optimization (

Towards Power Import and Regional Grid Interconnection: A Singapore‐Centric Energy Internet

Energy Internet, EarlyView.
ABSTRACT Singapore is accelerating its energy transition by pursuing large‐scale cross‐border renewable power import and regional grid interconnection. Targeting up to 6 GW of low‐carbon power import by 2035—equivalent to nearly half of its projected electricity demand—Singapore is poised to transform from a gas‐dominated urban power system into a ...

Post‐Arc Transient Dielectric Recovery Characteristics of Vacuum Interrupter in the Large‐Capacity Generator Circuit Breaker

High Voltage, EarlyView.
ABSTRACT Large‐capacity generator circuit breaker (GCB) based on vacuum interrupter technology is the key power equipment to ensure the safe operation of the power system. When the short‐circuit current was forced to cross zero, the large‐capacity GCB was difficult to generate a zero‐voltage environment through freewheeling, the vacuum interrupter (VI)
