A microgrid is defined as a local electric power distribution system with diverse DG (distributed generation) units, energy storage systems, and loads, which can operate as a part of the distribution system or when needed can operate in an islanded mode. Energy storage systems play a key role in improving security, stability, and power quality of the microgrid. During grid-connected mode, these storage units are charged from various DG sources as well as the main grid. During islanded mode, DG sources along with the storage units need to supply the load. Power electronic interfaces between the microgrid buses and the storage units should be able to detect the mode of operation, allow seamless transition between the modes, and allow power flow in both directions, while maintaining stability and power quality. An overview of bidirectional converter topologies relevant to microgrid energy storage application and their control strategies will be presented in this paper.

Small scale technologies to produce electricity close to the end users of power are employed by Distributed generation approach. Renewable energy based Distributed generators produce electricity production with the decrease in the global warming. The renewable energy based distributed generators (DG's) based on wind, solar energy, biomass, mini-hydro along with use of fuel cells and micro turbines will give massive advantages in near future. Distributed generation powered by various renewable and non-conventional microsources has become an attractive option for configuring modern electrical grids because of its advantages like environmental friendliness, expandability and flexibility. A microgrid paves a way to effectively integrate renewable energy based distributed generation. The microgrid consists of cluster of loads and distributed generators that operate as a single controllable system. The microgrid can operated in parallel with or isolated from the main power grid. The microgrid concept introduces the reduction of multiple reverse conversions in an individual AC or DC grid and also facilitates connections to variable renewable AC and DC sources and loads to power systems. Concerned about safe operation and protection of equipment has risen by the interconnection of DGs to the utility/grid through power electronic converters. Enhancement of local reliability, reduction of feeder losses, local voltages support, increased efficiency through use of waste heat, correction of voltage sag or uninterruptible power supply are the special requirement of the customers, the microgrid can be designed to meet their special requirements. In the present work the performance of hybrid AC/DC microgrid system is analyzed in the grid tied mode. Here we have developed a microgrid by using fuel cell system, wind turbine generator and battery. Also fuzzy logic controllers along with PI control mechanisms are implemented for the converters to properly coordinate the AC sub-grid to DC sub-grid. The results are obtained using the MATLAB/ SIMULINK environment.

This paper proposes an economic optimization method with two time scales for a hybrid energy system based on the virtual storage characteristic of a thermostatically controlled load (TCL). The optimization process includes two time scales in order to ensure accuracy and efficiency. Based on the forecast load and energy supply of the system, the first time scale is day-ahead economic operating optimization, carried out to determine the minimum operating cost for the whole day, and to find the period of greatest cost to which the second time scale optimization is applied. Using the virtual storage characteristic, the second time scale is short term detailed optimization carried out for these particular hours. By dispatching thermal load in this period and adjusting energy supply accordingly, we can find the optimal economic performance, and customer requests are taken into account to ensure satisfaction. A case study in Tianjin illustrates the effectiveness of this method and proves that a TCL can make a great contribution to improving the economic performance of a hybrid energy system.
