Power Generation Simulation of a Hydropower Reservoir System Using System Dynamics: Case Study of Karoon Reservoir System

, 2014
The system dynamics approach is an object-oriented simulation method based on feedback loops, flow diagrams, and flow and state variables, which can be used in the development of a water system’s operational policies and water-resource management.

Establishment of safety power range and subsequent commutation failure suppression strategy for hybrid cascaded HVDC system

International Journal of Electrical Power & Energy Systems
The hybrid cascaded high-voltage direct current (HC-HVDC) system integrates the benefits of both LCC and MMC technologies. However, the inverter LCC is prone to suffer subsequent commutation failure (SCF) when an AC fault occurs. Therefore, a coordinated

LLM-Powered User Simulator for Recommender System

Proceedings of the AAAI Conference on Artificial Intelligence
User simulators can rapidly generate a large volume of timely user behavior data, providing a testing platform for reinforcement learning-based recommender systems, thus accelerating their iteration and optimization. However, prevalent user simulators generally suffer from significant limitations, including the opacity of user preference modeling and ...

Distributed hierarchical control of islanded active distribution networks with dynamic consensus algorithm and adaptive virtual impedance

Frontiers in Energy Research
In the event of an upstream grid fault, the Active Distribution Network (ADN) can switch to autonomous operation, coordinating controllable Distributed Generators (DGs) and Energy Storage Systems (ESS) to maintain power supply reliability.

Soft Power, World System Dynamics, and Democratization: A Bass Model of Democracy Diffusion 1800-2000 [PDF]

This article uses Polity IV data to probe system dynamics for studies of the global diffusion of democracy from 1800 to 2000. By analogy with the Bass model of diffusion of innovations, as translated into system dynamics by Sterman, the dynamic ...

Montecarlo simulation based power system reliability evaluation

, 1998
Monte carlo simulation method of evaluating composite power system reliability uses the concept of sampling random numbers, which simulate the random failure of components of the power system. It requires more number of samplings.

Generator Power Optimisation for a More-Electric Aircraft by Use of a Virtual Iron Bird [PDF]

, 2006
A prodedure is developed to minimise the generator design power within the electric power system of a future more-/ all-electric aircraft. This allows to save weight on the generators and on other equipment of the electic power system.
