Abstract Although the penetration of renewable energy in power systems has been substantially increased globally last decade, fossil fuels are still important providing essential flexibility required to reliably maintain system balance. In 2019, more than one quarter generation Europe and over 40% UK’s electricity was from (mainly gas). For achieving net-zero greenhouse gas emission target arou...

The damping sensitivity analysis of interconnected power system low frequency oscillation is studied. The function of sensitivity analysis is implemented in the Small Signal Stability Analysis Package (SSAP). The paper mainly analyzes the sensitivities of oscillation modes with respect to the parameters of power system stabilizer (PSS) in the excitation systems of generators for a physical larg...

We investigated small-scale hydraulic power actuation systems using a system level analysis, where smallscale refers to systems generating 10 to 100 Watts output power, to determine whether the high power density advantage of hydraulics holds at small sizes. Hydraulic actuator system power density was analyzed with simple physics models and compared to an equivalent electromechanical system com...

In a mobile wireless system, fading effects can be classified into large-scale (long-term) effects and small-scale (shortterm) effects. We use transmission power control to compensate for large-scale fading and exploit receiver antenna (space) diversity to combat small-scale fading. We show that the interferences across the antennas are jointly Gaussian in a large system, and then characterize ...

as renewable energy increasingly penetrates into power grid systems, new challenges arise for system operators to keep the systems reliable under uncertain circumstances, while ensuring high utilization of renewable energy. this paper presents unit commitment (uc) which takes into account the volatility of wind power generation. the uc problem is solved with the forecasted intermittent wind pow...

State estimation is the foundation of any control and decision making in power networks. The first requirement for a secure network is a precise and safe state estimator in order to make decisions based on accurate knowledge of the network status. This paper introduces a new estimator which is able to detect bad data with few calculations without need for repetitions and estimation residual cal...
