Many power systems in the United States and elsewhere are experiencing simultaneous increases of the gas-fired and renewable portions in the generation profile. Both contributions are sufficiently clean to replace retiring generators, which are mainly coal-fired. Moreover, pairing gas and renewables is advantageous because the former is flexible enough to mitigate the exogenous fluctuations of the...
Size and complexity of power systems impose significant challenges for the power system analysis and control. As the power system becomes more complex there is a great need to develop improved and sophisticated tools for power system analysis and simulation. These tools should be able to accurately replicate real events that occur in electric power network and help to understand dynamics of changes...
The expected large-scale implementation of distributed generation (DG) requires a change in the current structure and operation of distribution networks. The future distribution network must be able to manage power flow in a bidirectional way, cope with uncertainties of renewable power generation and adjust to demands of more sophisticated customers. This paper introduces the concept of a power routing...
Microgrids are systems that integrate distributed renewable energy sources, controllable loads, and energy storage in a more economic and reliable fashion. In this paper we model the load and generation of two microgrids with wind farms to implement optimal power flow (OPF) using particle swarm optimization (PSO). The objectives are to achieve optimal dispatch of controllable loads and generators...
Based on the essence of self-organized criticality, this paper develops a novel model to study the cascading failures and blackouts in power systems with optimal power flow applications, which contains two types of dynamics, fast dynamics and slow dynamics. This model has also voltage stability analysis capacity and can reveal critical characteristics from the reactive power and voltage viewpoint...
