This paper present a control strategy for the operation of solar energy generation integrated with grid. Boost converter is used to achieve maximum power extraction from the available solar power. The buck converter and bi-directional converter connected with common dc bus, that dc bus connected different loads with constant dc voltage. The hysteresis current controller has implemented in inver...

The increasing penetration of renewable energy in recent years has led to more uncertainties in power systems. In order to maintain system reliability and security, electricity market operators need to keep certain reserves in the SecurityConstrained Economic Dispatch (SCED) problems. A new concept, deliverable generation ramping reserve, is proposed in this paper. The prices of generation ramp...

The networking and data transmission mode of the field mobile seismic station involves such matters as richness, real-time and effectiveness of seismic data. In this paper, we propose a networking and data transmission mode with CAN bus and embedded technology. In light of the effectiveness, distance, cost and construction relating to data transmission in the field environment, CAN bus was util...

Motor and its control technology are one of the main components of Hybrid Electric Vehicle HEV . To meet HEV’s fast torque response, vector control algorithm based on rotor fluxoriented and simulation model is concerned and modular designs for controller’s hardware and software are presented in the paper in order to build a platform to achieve the vector control of asynchronous induction motor....

Network reconfiguration is a nonlinear optimization procedure which calculates a radial structure to optimize the power losses and improve the network reliability index while meeting practical constraints. In this paper, a multi-objective framework is proposed for optimal network reconfiguration with the objective functions of minimization of power losses and improvement of reliability index. T...

The importance of preventing the voltage collapse is gaining importance due to increase in dependency on the use of electricity. This has compelled the utilities to maintain high system reliability. The evaluation of a power systems ability to withstand dangerous contingencies and to survive to a normal or acceptable operating point is a prerequisite for security analysis. Line outage often cau...

There are many approaches for improving the performance and reliability of secondary storage. The RAID (Redundant Arrays of Inexpensive Disks) is an example, but it still has a reduced performance for reconstructing data and using a large number of disks due to a bottleneck in the bus. We proposed DR-nets (Data-Reconstruction networks) to remove this bottleneck. In DR-nets, each node is connect...

This paper proposes a new index to determine the static voltage stability of the load buses in a power network for certain operating conditions and hence identifies load buses which are close to voltage collapse. The proposed index is formulated from the quadratic equation derived from a twobus network and is computed using the apparent power and the line impedance. The proposed index shows how...
