Reactive power management at the transmission–distribution interface with the support of distributed generators – a grid planning approach

Impact Analysis of Large-Scale Wind Farms Integration in Weak Transmission Grid from Technical Perspectives

“…The abovementioned concerns compliment power quality (PQ) issues that produce fluctuating output power in LSWF, which affect voltage stability [17,18], frequency stability [18], harmonics [17], fault ride through (FRT) [19], and the power factor (PF) [20]. RER and Q impact a point of common coupling (PCC) [21].…”

“…PQ impacts consider wind system integration evaluated through a steady-state time series analysis with historical data and present an impact assessment in terms of cases and scenarios from a wide range of best to worst [8,18,21]. The study conducted in [20] presents a review regarding classification of wind technology classifications from PQ and grid code perspectives. The WTG is based on types such as the squirrel-cage induction generator (SCIG), wound rotor synchronous generator (WRSG), and doubly fed induction generator (DFIG) [2,6,20].…”

The WTG is based on types such as the squirrel-cage induction generator (SCIG), wound rotor synchronous generator (WRSG), and doubly fed induction generator (DFIG) [2,6,20]. A study in [24] reviewed wind farm challenges and solution technologies predominately from the viewpoint of PQ, PF, insufficient Q, and power balance.…”

“…Apart from the abovementioned issues, integrating the LSWF into transmission grids causes a higher susceptibility to Q compensation issues, which have been evaluated across various scenarios of several applications but predominately in flexible AC transmission devices (FACTS) [15,17,20,23,[25][26][27][28][29]. Internationally, on-load tap changers have been used as a first line of defense for the grid's voltage stability; however, it has limitations regarding response speed [25].…”

Low‐voltage ride‐through operation of grid interfaced solar PV system enabling harmonic compensation capabilities

“…Due to low maintenance cost, learning ability, market growth and nascent technologies, the roof‐top solar photovoltaic (PV) technology is booming as a distributed generating system. The voltage profile of the distribution grid is improved by solar power generation (SPG) coupled voltage source converter (VSC) at common coupling point (CCP) [2].…”
