Abstract—This paper presents hierarchical operation strategies which are minimizing operation error between day ahead operation plan and real time operation. Operating power systems between centralized and decentralized approaches can be represented as hierarchical control scheme, featured as primary control, secondary control and tertiary control. Primary control is known as local control, fea...

the biggest challenges faced in big cities are greenhouse gas emission and growing energy needs. efficient utilization of existing infrastructures has a prominent role in response to the challenges. energy hub approach embraces performance of different energy networks. energy hub is defined as a super node in electrical system receiving distinctive energy carriers such as gas and electricity in...

Microgrids can be considered as controllable units from the utility point of view because the entities of microgrids such as distributed energy resources and controllable loads can effectively control the amount of power consumption or generation. Therefore, microgrids can make various contracts with utility companies such as demand response program or ancillary services. Another advantage of m...

We present preliminary results from compiling the highlevel, functional and data-parallel programming language SaC into a novel multi-core design: Microgrids of Self-Adaptive Virtual Processors (SVPs). The side-effect free nature of SaC in conjunction with its data-parallel foundation make it an ideal candidate for auto-parallelisation. Notwithstanding these favourable pre-conditions, schedulin...

Wind energy conversion systems are now occupying important space in the research of renewable energy sources with microgrid. The main challenge in wind power generation is power quality problem and their connection with the distribution network in microgrid. The main factor behind poor power quality is the impact of harmonics in current and voltage in power network. In microgrid the converter a...

Microgrids have a long history. In fact, Thomas Edison‘s first power plant constructed in1882 – the Manhattan Pearl Street Station – was essentially a microgrid since a centralized grid had not yet been established. By 1886, Edison‘s firm had installed fifty-eight direct current (DC) microgrids. However, shortly thereafter, the evolution of the electric services industry evolved to a state-regu...

This paper presents an optimal scheduling model for a microgrid participating in the electricity distribution market in interaction with the Distribution Market Operator (DMO). The DMO is a concept proposed here, which administers the established electricity market in the distribution level, i.e., similar to the role of Independent System Operator (ISO) in the wholesale electricity market, sets...

This paper presents the importance of deployment of distributed energy resources as a promising aspect which is emerging as a future power system as microgrid in the power community worldwide. The basic concepts of microgrid technology including its operational and control techniques are presented briefly in simplified manner. The application and prospect of microgrid in Indian power scenario a...

This paper presents dynamic models of distributed generators (DG) and investigates dynamic behaviour of the DG units within a microgrid system. The DG units include micro turbine, fuel cell and the electronically interfaced sources. The voltage source converter is adopted as the electronic interface which is equipped with its controller to maintain stability of the microgrid during small signal...
