Meta-heuristic optimization methods applied to renewable distributed generation planning: A review
Due to its proven efficiency and computational speed, the most recent developed meta-heuristic optimization methods are widely used to better integrate renewable distributed generation (RDG) into the electricity grid. The main objective of this paper is to obtain a better knowledge of current trends in meta-heuristics applied to optimally integrate RDGs to the distribution network. This is a review of well known meta-heuristic approaches, used to solve the problem of optimal renewable distributed generation allocation planning (ORDGAP). In this context, some research gaps were mentioned, and recommendations were proposed to expand the scope of research in this field
Voltage Stability Assessment and Control Using Indices and FACTS: A Comparative Review
The problem of voltage stability is becoming a more acute and indispensable topic given the major and sensitive role it plays in the electrical system. It can be considered a major factor in the initiation of blackouts around the world. Hence, the need for reliable and fast tools to detect and control the approach of instability points throughout the network, namely, voltage stability indices and flexible alternating current transmission systems (FACTS) devices for the control and management of the electrical network. In this paper, an update on the existing blackouts in the world has been presented. Based on the brief overview of the most significant definitions of voltage stability presented in this work, a new definition of voltage stability has been proposed. A detailed comparative study on voltage stability analysis methods has been conducted. Furthermore, an exhaustive discussion on the various voltage stability indices and FACTS devices existing in the literature with their contribution to voltage stability prediction and improvement has been proposed
