To justify the large deployment of the microgrid concept, economic operation should be guaranteed. But non-linearities present in the nature of microgrid components and network make the scheduling process complex. Again, non-linear solution strategies do not guarantee global convergence. Therefore, efficient but linear model for microgrid resource scheduling algorithms are gaining interest in present time due to its simplicity and fast computation. On the contrary, for peak demand management, flexible load scheduling is a viable and easiest option to the microgrid operators to minimize the customers' dissatisfaction. This article serves the aforementioned purposes by designing a linear model for microgrid scheduling by implementing demand side management strategies to manage flexible appliances aiming for peak demand reduction. The strategy is implemented on a practical Indian distribution system consisting of commercial and residential loads to prove its efficacy.
Standalone Microgrid: A Sustainable Option for Energy Handling

A possible solution is standalone or off-grid microgrid. Standalone micro-grid reduces the load on grid. In this way, we can reduce energy generation by conventional ways which will eventually decrease carbon emission to the environment. In this paper we have modelled a standalone microgrid for Rewa Engineering College and will discuss the advantages and disadvantages of standalone microgrid based on the model.

In last few decades, the environmental pollution and limited resources for non-renewable energy led us to shift towards more sustainable renewable energy resources and smart efficient appliance for electricity saving. In modern electricity system Hybrid grid is much more energy efficient and reliable technology. In Hybrid system has both types of AC and DC supply and appliance are included with proper power modulator. In this paper optimized a hybrid grid with different types of DGs and AC-DC loads in linear platform using MILP algorithm with taken the example of a home as well as compared the electricity bill with previous condition. Here we done the work for automation of home as well as optimized hybrid grid and saw many benefits over the conventional grid.

Firstly the waste water treated in Sewage Treatment plant. It includes physical, chemical and biological contaminants. Its objective is to produce an environmentally. Here the solid waste (treated sludge) suitable for disposal of reuse (usually for fertilizers) and treated water used for generating electricity by a small Hydro power plant. Treated water of sewage at a high pressure or flowing with a high velocity can be used to run turbine or water wheel coupled to Generator and therefore of electrical power is becoming more and more popular as it is reliable and requires least maintenance and care. Output power has been estimated for available different head and flow rate of the waste water. Various types of the turbine-generator sets for different available head have also suggested for reliable operation of the developed this plant. The main advantage of this power plant is an independent power pl...

Microgrid facilitates penetration of renewable energy sources into the existing distribution systems to reduce the overall carbon footprint of the globe by reducing the dependency on the main grid. Efficient but linear microgrid resource scheduling algorithms are gaining interest in present time due to its simplicity and fast computation. This research paper aims to serve the purposes by designing a mixed integer linear programming based microgrid scheduling problem while various types of scenario, minimize the electricity cost for the utilities also maintain the generation and load balance. The strategy is implemented on a small microgrid to prove its efficacy .In this paper mainly optimal scheduling of microgrid has been done in various scenario, and obtained there global minimum electricity cost to the help of mixed integer linear programming (MILP) algorithm. Microgrid is a small scale type of power grid, which provides the energy locally, its offers integration between distributed energy resources and the locally connected loads. Microgrid able to be operated with the main grid and in standalone mode also ability to transitions between these two modes, the mode of operation of microgrid is depends on the system operating condition. The reliability of power grid is improving more when it's integrated with the Microgrid and works together. Power exchange with the upper stream grid is done through the point of common coupling (PCC). Microgrid having renewable energy resources i.e. PV, Wind and non-renewable energy resources, DG, FC, and MC connected with the Battery storage type system and locally connected loads. So it is a very reliable scenario, main grid with the microgrid, it is more beneficial, economy and stable types of system.
