In this paper, the application of high reliability distribution system (HRDS) in the economic operation of a microgrid is studied. HRDS, which offers higher operation reliability and fewer outages in microgrids, is applied to looped networks in distribution systems. The microgrid model in this study is composed of distributed energy resources (DER) including distributed generation (DG), controllable loads, and storage. The microgrid would utilize the local DER as well as the main grid for supplying its hourly load economically which is subject to power quality and reliability requirements. The HRDS implemented at Illinois Institute of Technology (IIT) is used as a case study along with the local DER to increase the load point reliability and decrease the operation cost of the IIT microgrid. The availability of distribution lines, main grid supply, and microgrid generation is considered using the Markov chain Monte Carlo simulation in the microgrid scenarios. The reliability indices based on frequency and duration of outages are measured at the microgrid level and the load point level, and the potential system enhancements are discussed for improving the economic operation of the IIT microgrid.Index Terms-High reliability distribution system, microgrid economics, stochastic security constrained unit commitment, storage.

A mathematic model of battery energy storage system (BESS) and integrated load model are built, and a multi-index nonlinear coordinated control scheme for the system is proposed. As a new FACTS facility, BESS can regulate active power and reactive power of the power bus synchronously. Simulation results show that BESS has the advantage of availably reducing the influence of the power bus subjected to a disturbance on load voltage and active power. It can enhance the control accuracy of output variables and voltage stability, improve the power quality of load. With the ability of BESS, the dynamic characteristics of load voltage and active power can be controlled more smoothness, and the responses of the system is more speediness.

“…Severe situation now gives rise to the LVRT (Low Voltage Ride Through) technology. LVRT of wind power means that wind generator can be connected to grid like thermal power generators when voltage sags in the grid with high proportion of wind power [2,3]. Meanwhile, there should be some reactive power offered to power grid to help to rebuilt grid voltage.…”

To minimize the influence of power grid with wind power generation resulted by voltage sags with short duration, a paralleled integrated control device of squirrel-cage induction wind generator LVRT (Low Voltage Ride Through) is proposed which adds paralleled module circuits to conventional wind generator. With closed-loop hysteresis current control based on instantaneous reactive power theory and rated voltage control, this device can achieve reactive power compensation in normal operation and voltage stability when voltage sags. Power produced by wind generator is consumed during the sag and wind power generation system is connected to grid all the time. Simulation models about the device were built based on PSCAD / EMTDC platform and the analysis verifies the device’s achievement of LVRT.
