The penetration of large-scale renewable energy puts an urgent demand on increasing
power grid flexibility. From the power grid perspective, transmission congestion has become …

Coordinated planning is an effective method to balance investment costs and benefits in
achieving high renewable target under the renewable-driven power system expansion …

Although wind power generation improves decarbonization of the electricity sector, its
increasing penetration poses new challenges for power systems planning, operation and …

Phase shifters (or phase shifting transformers) are used in power grids to regulate the flow of
real power. They are used to prevent overloading of transmission lines and also to regulate …

Virtual energy storage systems (VESS) are important new equipment for distribution
networks, consisting of battery energy storage systems (BESS) or flexible loads (FL), that …

Considering the independency of areas as a challenge in multi‐area economic dispatch
(MAED) problems, this study presents a novel parallel process MAED to preserve …

The power system with flexibility provision will lead to the expansion of the utilization of
renewable energy resources. Providing flexibility is one of the basic challenges for power …

AC optimal power flow (ACOPF) is a nonlinear and non‐convex problem that might include
various constraints. The methods in the literature for solving this problem may suffer from …

The increasing integration of renewable energy sources has a long-lasting impact on the
electrical grid, and the liberalisation of the energy sector has significantly changed its …

In this paper we propose a generalized branch model to be used in DC optimal power flow
(DCOPF) applications. Besides AC lines and transformers, the formulation allows for …
