Reactive Power Cost From PV Inverters Considering Inverter Lifetime Assessment
IEEE Transactions on Sustainable Energy, 2019Photovoltaic (PV) system inverters have been frequently utilized for reactive power support in the literature. Although the benefits of PV reactive power for the grid have been quantified, the costs incurred by the PV owner have largely been ignored ...

Every optimization problem employed to study electric power systems consists of an objective function and a group of constraints to be observed by this function that concurrently define the problem itself. The main constraints associated with the problem of reactive power planning are related to load flow equations.

Short-term industrial reactive power forecasting
International Journal of Electrical Power & Energy Systems, 2019Reactive power forecasting is essential for managing energy systems of factories and industrial plants. However, the scientific community has devoted scant attention to industrial load forecasting, and even less to reactive power forecasting.

Reactive Power Management is a critical issue when dealing with the planning and operation of power networks with high wind energy penetration. Reactive Power Management entails the requested operation and planning actions to be implemented in order to improve the voltage profile and the voltage stability in power networks [1].

Over the years, voltage performance of a power system has received attention from both analysis and improvement points of view. Although voltage magnitudes are, normally, of main concern, during the last, perhaps, two decades, voltage stability is also received attention in literature. In this section, we try to briefly, differentiate between these two
