Renewable energy sources (RES) should be prioritized because they provide a clean and sustainable energy supply and are abundant in nature. Demand side management (DSM) optimizes the scheduling of flexible loads to reduce peak demand and improve the load factor, while keeping daily demand unchanged. The test system in this research employs a dependable and effective hybrid optimization tool to plan the DGs of a dynamic system in a way that matches low active power production costs with low pollutant emissions. The fitness functions used in the test system were non-linear due to the presence of the valve point effect (VPE). The costs and emissions were evaluated for various fitness functions which included involvement of wind, DSM, and different types of combined economic emission dispatch (CEED) methods. The test system's peak demand was cut by 12% and the load factor was raised from 0.7528 to 0.85 when DSM technique was used.

Vehicle to Grid (V2G) is specially designed to empower the utility grid by feeding back the stored energy from batteries of the vehicles to the grid. V2G technology reflects the bidirectional power flow between the utility grid and higher thrust batteries of vehicles. When a grid needs extra power it can draw from each individual vehicle when energy is abundant. It’s a functional awareness once we consider that the maximum number of vehicles is parked in parking lots any point of time which reflects a huge amount of energy kept ideal without any use. This V2G will enables us self-sufficient by managing our own energy effectively through our process. It plays a crucial part in helping to ‘balance’ the grid. Under the scenario of a sustainable world, electric vehicles are one of the fundamental parts of the utility system by functioning as distributed energy sources in the vision of the smart grid. Electric vehicles can provide additional storage and enhance grid stability by pumping the required amount of additional power. With this process, the owner of the electric vehicle can earn some reward points in terms of cash. With the help of the electric vehicles movement in the existing grid, the amount of renewable energy inclusion to the system will be enhanced. Electric vehicles can stabilize the grid integration through penetration of return energy from the vehicle to grid during peak load time and during off-peak, it can store charge. V2G shows a significant role during load shedding. These kinds of distributed generation systems can be feasible to crucial load during an outage. This paper proposes a replacement of the traditional control arrangement of a battery system with an intelligent battery management and control system which is working in association with cloud computing. The proposed algorithm offers the computational allocation of PEV to work efficiently when the number of vehicles is more.

The main drawback of battery storage system is they are not eco friendly and every 3 to 4 years they have to be replaced. The popularity of the renewable energy sources are favoring the Solar PV power generation but the financial viability of the project is not attractive because of the usage of the Batteries. In this project, a new methodology has been suggested to replace the batteries with Fuel cell based power generation. This model analyzes a standalone PV-hydrogen system. Excess solar power goes to the electrolyzer, which generates hydrogen for storage in the hydrogen tank. The fuel cell generates electricity using the stored hydrogen as fuel. The round-trip efficiency of the hydrogen storage system is not more than 50%. Because so much power is lost in the storage system, the energy production of the PV array exceed the electrical load. Although the average electric load is only 8.3 kW, the ...

The increase in energy consumption is due to increased in number of building that is being constructed these days. The material that is used to build a general building now days mostly consists of non-renewable materials which are neither long lasting nor Energy Efficient. These are health hazardous and less eco-friendly too. As far as economist is concern, though these material gives the low initial cost for making a building but leads to high energy consumption expenses and a high maintenance cost which results in increasing the overall cost of the building. In this paper we will observe the effect of some of the component of green building like roof, glass etc and its different kinds which is use to construct the green buildings. And also we will find how much extent this green glass reduces the overall power consumption of the building as compare to normal glass by using simulation process(Using ECO-nirman whole building ...

That is the reason why we give emphasis on designing the buildings in such a way that, the internal environment is isolated from the external environment. At the same time, this leads to very high energy consumption. So, it has become very important to break this trend of constructing building, and adopt new ways so that minimal energy is consumed and maximum is saved for our future generation; without compromising the luxury. This paper is based on the implementation and simulation after the analysis of a building and will rate it as per the guidelines for providing an energy star rating. Here we will study in practical about the energy efficiency of the building by taking the conventional loads and also by implementing energy star rating. Finally by taking down the readings we will draw the simulation curve and will see how much energy consumption is reduced and the ene...

One of the clear ideas is that electric vehicle function as a distributed energy source and provide additional services to the electricity grid. In the vehicle-to-grid (V2G) model, collection of EV is used for the delivery of energy services, including supplementary services to the grid. Contribution in the V2G outline may involve supplementary charge and discharge of the EV batteries. Vehicle to grid can provide the distributed stored power in terms of rotatory reserve power to the utility grid. V2G power has the potential to revive the frequency deviance observed at the charging terminal and the required battery SOC (State-of-Charge). In case of grouping an enormous number of electric vehicles at a distribution utility grid bus, operation in V2G mode may be used for grid support during faulty situations. In this paper, the proposed vehicle control procedure scheme is executed to an electric vehicle and battery charging system. The results describe the proposed smart battery energy management prediction service considerably reduces the actual number of communications of electric vehicles with charging units and grid as well as forecasting the load demand. Simulation results show that the suggested method significantly performed the rule-based method.

From this point of view, the DC/DC converter is particularly suitable for the application of the switching mode control in photovoltaic application, because of its controllable states. The switched- mode dc-dc converters are some of the most widely used power electronics circuits for its high conversion efficiency and flexible output voltage. This leads to the requirement of more advanced control methods to meet the real demand. Many control methods are developed for the control of dc-dc converters. Conventionally, the dc-dc converters have been controlled by linear voltage mode and current mode control methods. These controllers offer advantages such as fixed switching frequencies and zero steady-state error and give a better small-signal performance at the designed operating point.

The hysteretic controlled converters response to disturbances and load change right after the transient take place and they give excellent transient performance. It does not require the closed loop compensation network and results with a lesser component count and small size in implementation. Hence, hysteretic control is considered as the simplest and fastest control method. The dc-dc buck converter employing current hysteresis control scheme is given in thesis. The result shows that hysteresis control converters have inherently fast response and they are robust with simple design and implementation. A hysteretic current control technique for a tri-state buck converter operating in constant switching frequency is designed and its behavior is studied by making the use of essential tools of sliding mode control theory because dc-dc buck converter is a variable structure ...

The development of high performance control strategies for AC drives, driven by the requirement of industry, has resulted in a rapid evolution during the last two decades. The Predictive Torque Control (PTC) technique has features of precise and quick torque response. This method is gaining popularity in the industry due to its simplicity and high dynamic performance.The control strategy combines the use of classical PI controller to obtain good steady state response and a predictive controller scheme to achieve good dynamic response. The main characteristic of predictive control is the use of a model of the system for predicting the future behaviour of the controlled variables. This information is being used by the controller to obtain the optimal actuation, according to a predefined optimization criterion. In predictive control scheme, the control objectives are defined as a cost function, which is to be minimized to have greater flexibility to include constraints which results in low computational complexity compared to Direct Torque Control (DTC) scheme. PTC offers high dynamic performance, accurate speed response. The PTC based voltage source inverter fed induction motor drive is capable of offering four quadrants in the torque-speed plane of operation like, forward motoring, forward generating, reverse generating and reverse motoring. To validate the proposed algorithms mathematical models were developed for induction motor, estimation of torque and flux and control logic. These models were integrated and simulations were carried out using Matlab/Simulink. Variation in stator currents, speed, electromagnetic torque developed and stator flux during different operating conditions such as starting, steady state, sudden change in load and speed reversal are observed with the help of waveforms and results are discussed.
