-A microgrid can play a significant role for enlargement of renewable energy sources and emission reduction because it is a network of small, distributed electrical power generators operated as a collective unit. In this paper, an application of optimization method to economical operation of a microgrid is studied. The microgrid to be studied here is composed of distributed generation system(DGS), battery systems and loads. The distributed generation systems include combined heat and power(CHP) and small generators such as diesel generators and the renewable energy generators such as photovoltaic(PV) systems, wind power systems. Both of thermal loads and electrical loads are included here as loads. Also the emissions trading scheme to be applied in near future, the cost of unit start-up and the operational characteristics of battery systems are considered as well as the probabilistic characteristics of the renewable energy generation and load. A mathematical equation for optimal operation of this system is modeled based on the mixed integer programming. It is shown that this optimization methodology can be effectively used for economical operation of a microgrid by the case studies.

“…Table II presents the probability of SARF I 80% and SARF I 90% for specific sag frequency. The accuracy of the estimation is evaluated by the quantity called uncertainty ( ), which is calculated as (5). Obviously, the estimated results equivalent to 50 years' monitoring time duration are of high confidence level.…”

“…This tendency results in the current convention of disconnection of DG during fault becomes unreasonable in the future [5]. The grid code is proposing more requirements on voltage support for DG by remaining connected to the utility grid This work is funded by Alliander N.V., Arnhem, the Netherlands Mao Li, Yu Xiang and Sjef Cobben are all with Eindhoven University of Technology, the Netherlands (e-mail:m.li@student.tue.nl).…”

Short circuit (SC) fault is one of the most severe disturbances faced by the power system. SC faults not only lead to high SC currents but also cause voltage sag in a wide area. In this paper the voltage sag problem caused by SC fault are estimated based on the probabilistic SC concept. The research is based on a typical Dutch Medium Voltage distribution grid where the penetration of Distributed Generation (DG) is experiencing rapid growth. Fault Ride Through (FRT) capability will be obligatory for all types of DG system in future grid code which is different with currently situation. However, SC contribution from Voltage Source Converter (VSC) based DG is neglected according to IEC 60909 standard and there is no available model to consider FRT behavior of VSC-DG yet in the simulation software DIgSILENT PowerFactory. Therefore an equivalent model is developed in PowerFactory in order to emulate VSC-DG's FRT capability and study its effect on the voltage sag estimation results. The simulation results show that the probability of occurrence of severe voltage sag is reduced and the system overall voltage sag performance is improved both due to the voltage support effect during FRT.
