Many countries around the world have changed the economics of their electricity markets
from monopolies to oligopolies in an effort to increase competition. The restructured …

This paper proposes a new multi-objective stochastic market settlement model for a coupled
energy and reactive power ancillary service, named as MOSMS-CERP model, for a …

In a deregulated environment, when talking about electricity markets, one usually refers to
energy market, paying less attention to the reactive power market. Active and reactive …

Distributed generations (DGs) are main components for active distribution networks (ADNs).
Owing to the large number of DGs integrated into distribution levels, it will be essential to …

MicroGrids represent a new paradigm for the operation of distribution systems and there are
several advantages as well as challenges regarding their development. One of the …

This paper presents a novel stochastic programming model for active and reactive power
scheduling in distribution systems with renewable energy resources. In distribution systems …
