Parameter Identification With PMUs for Instability Detection in Power Systems With HVDC Integrated Offshore Wind Energy

Optimal Power Flow in Hybrid AC and Multi-terminal HVDC Networks with Offshore Wind Farm Integration Based on Semidefinite Programming

“…In addition to the onshore wind farms, offshore wind farms also draw a lot of attention because of better wind quality and limited inland sites to build new wind farms [2]. High voltage direct current (HVDC) technology is one of the most favorable options for the integration of offshore wind farms to deliver the power for inland customers [3]. Multi-terminal HVDC grids are emerging as a very promising concept to support the mesh DC networks such as SuperGrid [4] proposed in Europe, and therefore draws a lot of interests from industry and academia.…”

Accurate and efficient modelling of grid tied inverters for investigating their interaction with the power grid

“…The modelling of RESs based on RMS models is suggested in [6], [7]. Moreover, an HVDC equivalent model founded on circuit theory for the quasi steady-state time scale is suggested in [8] for enabling long term stability analysis. However, these models cannot be accurate under transient events or non-linear conditions (i.e., harmonics, asymmetries) and furthermore, a realistic response of the synchronization method of RES cannot be properly considered in RMS simulations.…”

Modified Thevenin‐based voltage instability indicator and load shedding approach for MCF connected network

“…Recently, measurement-based methods are more utilised for real-time voltage stability evaluation of power networks [7][8][9][10][11][12][13][14][15][16]. These methods are classified into local and global approaches.…”

“…These methods are classified into local and global approaches. Local approaches are commonly based on the estimation of equivalent Thevenin parameters from a local load bus [7][8][9][10][11][12]. However, global approaches use the gathered data from phasor measurement units (PMUs) installed at different buses [13][14][15][16].…”

“…On the other hand, local voltage instability indicators have some interesting features such as simplicity and low computational burden. The local indicators are classified based on the application of system variables such as the power flow of lines [8,9] and the voltage of buses [10][11][12]. Voltage instability risk indicator (VIRI) is a member of the second group and it is inspired from the maximum power transfer theorem.…”
