In this paper, a new structure for reactive power market is presented. Considering reactive power losses caused by active power flow in the reactive power market is the main purpose of this paper. Hence, this study tries to improve reactive power market and create fair competition in reactive power generation.

2 I. INTRODUCTION Power system economics procedure includes of two aspects: active power regulation and reactive power dispatch. This forms a global optimization problem of a large-scale industrial system.The reactive power problem is less manageable to solve than the active power problem due to its more complicated relationship between variables. The reactive power problem is largelyassociated...

A new single-phase transformerless grid-connected PV inverter is presented in this paper. Investigations in transformerless grid-connected PV inverters indicate the existence of the leakage current is directly related to the variable common-mode voltage (CMV), which is presented in detail. On the other hand, in recent years it has become mandatory for the transformerless grid-connected PV inver...

Penetration of distributed energy resources (DERs) such as wind, solar and battery units are rapidly increasing in distribution power system (DPS). In view grid reliability efficiency, cyber physical secure these highly important since it can directly impact operations. This paper investigates the dynamic behavior during cyber, natural strikes on reactive control DER units. Various fault scenar...

Abstract Recently, there is vast progress in the integration of renewable energy generators (REGs) into power grid. The reactive power, which indeed a fundamental system factor being influenced highly by penetration levels. As consequence, this has paved way toward generation steady‐state voltage and dynamic/transient stability issues. Therefore, to provide sustainable dependable grid, it impor...

Rising penetration of photovoltaic (PV) power also poses several threats to electrical system which demands proper inverter control schemes be designed. One major issue is that as PV systems are inherently non-inertial in nature, they do not participate regulating voltage or reactive and hence become highly sensitive external disturbances. Any perturbation frequency may cause some serious conse...
