This paper focuses on the operation of a microgrd which is connected to the main grid and can exchange power with it. To do so, the problem is modeled using mixed-integer linear programming (MILP). In the next step, an evolutionary algorithm known as Strength Perto Algorithm (SPA) is utilized to...

In many industries such as power system, economic operations problems are usually nonconvex problems that are hard to be solved. This paper presents a novel YALMIP-based nonconvex quadratic programming model as a tool to find solution for which is accurate, and there is no need to convexify the...

The chaotic systems play a critical role in a wide range of communication systems, form both economical and technical. Recently, a new fractional-order chaotic system was proposed and dynamical analysis was investigated. Here, we focus on synchronization of the drive and response systems, which...

Security Constraint Unit commitment (SCUC) is one of the challenging economic problem of the power utilities due to the ON and OFF status of the units. Indeed, in SCUC we should determine the status of the units for the day-ahead horizon. SCUC is a mixed-integer linear problem (MILP), which is...

Islanded microgrid (MG) is a microgrid which is disconnected from the main network and therefore it is safe and has lead to one of the most important challenges in the power system operation. In the case of higher price in the market, the islanded MG offers a lower operational cost. On the other...
