Description: Production of energy in centralized power plants
and transmitted via transmission lines to the customers is
always with high power losses. Distributed generation
(DG) especially renewable energy resources (RES) and
energy storage systems (ESS) through distributed system
are very cost saving and sometimes inevitable. If these
small DGs want to connect to power system and participate
in energy market directly, both distribution and energy
market would have many problems with control such a high amount of information and small supplies of DGs. Application of virtual power plant (VPP) as an aggregation of some DGs with own local energy management system and some fix and variable loads is a suitable solution for DGs and networks problems.

Description: In a deregulated utility environment financial and market forces will demand a more optimal and profitable
operation of the power system with respect to generation, transmission and distribution. Power electronic
equipment such as flexible AC Transmission systems (FACTS) opens up new opportunities for controlling power
and enhancing the usable capacity in the existing system. A Static synchronous compensator (STATCOM) based
on the voltage Sourced inverter is a widely used shunt FACTS device. This paper deals with the basic simulation
of STATCOM for two machine system and demonstration of transient stability enhancement using STATCOM
through Matlab/Simulink/Power system Computer Aided design (PSCAD). Platform: |

Description: 2.1 optimal power flow analysis:
The main aim of Optimal Power flow (OPF) algorithm is to capture a steady state operating point. Generation cost, loss are curtailed by steady state operating point. Further, it also maximizes load ability preserving a suitable system representation in terms of parameters of generators (real and reactive powers, line flow limits, output of various compensating devices etc.) . Usually , classical optimization methods were used but as the technology has advanced and integration of FACTS devices in the power system, the traditional concepts and practices of power systems are placed over by an economic market management. . Therefore, OPF has become complex in nature. So, Artificial Intelligence (AI) methods are used which can solve higher complexity problem than OPF.
