Microgrids are increasingly being considered to provide electricity for the expanding energy demand in the grid distribution network and grid isolated areas. However, the technical challenges associated with the operation and controls are immense. Management of dynamic power balances, power flow, and network voltage profiles imposes unique challenges in the context of microgrids. Stability of t...

This study investigates the potential application of Stateflow (SF) to design an energy management strategy (EMS) for a renewable-based hybrid system (HES). The SF is extended finite state machine; it provides platform design, model, and execute complex event-driven systems using interactive graphical environment. HES comprises photovoltaics (PV), storage units (ESU) diesel generator (Gen), int...

This paper deals with the development of a control technique for voltage source converters (VSCs) as an interface between renewable energy sources (RESs) and power grids. The lack inertia in converter-based generators their unconventional dynamic behavior increase negative impacts on grid, unlike operation conventional synchronous (SGs). In this sense, proposed emulates SGs loop interfaced conv...

In this project a Microgrid consisting of different distributed generation (DG) units are presented. These distributed generation (DG) units are connected to the distribution grid. The distributed energy resources are necessary to saving the energy for future use. Here an Energy-management algorithm is implemented to coordinate the operations of the different DG units in the Microgrid for grid-...

In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network. However, it is not practical in real networks due to the relatively expensive cost of PMUs and other technical limitations. Optimal PMU Placement (OPP) is an optimization p...

This paper presents a novel interactive multi-level planning strategy for the energy management of distribution networks with clustered microgrids (CMGs). CMGs are group multiple renewable resources that comprise various technologies, such as photovoltaic systems, wind turbines, micro turbines and electric vehicles. study develops an innovative optimization framework coordination between in low...

The power system of the future is an intelligent grid capable of a number of functionalities. These functionalities will enable the power system to exhibit behaviours that enhance the reliability and security of the power system. This modern power system is called the smart grid. In order to ensure proper operation of the smart grid, it is important that its constituent parts operate satisfacto...

A microgrid formed by a cluster of parallel distributed generation (DG) units is capable operating in either islanded mode or grid-connected mode. Traditionally, using model predictive control algorithms, these two operation modes can be achieved with separate and different cost functions, which brings complexity hence, compromises system reliability. In this article, unified voltage current st...
