Optimum Reactive Power Dispatch for Alleviation of Voltage Deviations
TELKOMNIKA (Telecommunication, Computing, Electronics and Control), 2012 This paper presents a non-linear optimization algorithm for alleviation of under-voltage and over-voltage conditions in the day-to-day operation of power networks. Voltage control for varying load and generation conditions can be achieved by coordinated control of switchable shunt VAR compensating (SVC) devices, on load transformer taps (OLTC) and ...

Propagation of Voltage Deviations in a Power System [PDF]
Electronics, 2021 The paper deals with voltage profiles in a power system. The analysis of these profiles is important due to the requirement that the Root-Mean-Squared (RMS) values of nodal voltages should be within certain ranges, as well as to ensure desired power flows in a power system. In both cases, it is desirable to indicate points in a power system where it is

Voltage deviations influence on asynchronous characteristics of powerful asynchronized turbogenerator [PDF]
Energy engineering and control systems, 2020 The widespread applying of electrical grids with voltage classes 330 and 750 kV with powerful units of nuclear and heat power plants creates a set of problems with normal modes ensuring in the Ukrainian energy system. Due to sufficiently great transverse capacitance of such overhead lines, significant amounts of reactive power excess are possible in ...
