Power system consist of generation, transmission, and distribution of power to clients. To meet the increasing demand the power sector has developed improving the quantity of tools, especially costly parts needed for power systems. Power generation and demand should be constantly adjusted to improve the operating effectiveness. The power system has disadvantages such as poor power quality and the significant expense of generation, which face difficulties in meeting the objective of supply of electrical energy. In this paper, a wind power plant model using MATLAB has been taken. When wind turbine is connected to existing power systems, wind turbines can cause a number of issues related to the system stability and power quality. To maintain the output power of system at desired values, an ANFIS system is designed as a controller for the power output of a variable speed wind power generation system. Membership functions are the building block of ANFIS, hence ANFIS has been trained with different membership function and results are obtained. Along with that, in an isolated wind plant, the variation in wind speed synchronous condenser need to increase the VAR generation due to which larger capacity synchronous condenser has to be installed. So ANFIS controller is designed to change the pitch angle so as to maintain the VAR generation of synchronous generator. The adequate result has been obtained, and it is found that the Gaussian type membership function gives the best result at higher wind speed and the variable generation has been controlled.
Contingency selection and ranking using fast and accurate method has become a main issue to ensure the secured operation of power systems. This work proposes multi-layer feed forward artificial neural network (MLFFN) and radial basis function network (RBFN) to demonstrate the static security assessment. In this, the composite security index which is capable of accurately differentiating the secure and insecure cases of power system based on contingency selection, and ranking are done. For each contingency in power system, the composite security index is computed using conventional Newton-Raphson load flow analysis. The MLFFN and RBFN takes all possible loading conditions and probable contingencies as input and assess the system security by screening the credible contingencies and ranking them in the order of severity based on composite security index. The proposed approach is demonstrated by considering the IEEE 30 Bus system using MATLAB simulation.
Solar panels are being increasingly installed on roof tops to generate electricity. This paper analyses the performance of grid connected PV system which consists of 3 case studies for the same plant with different orientations. The importance for the change in the collector plane orientations is briefly analyzed by different case studies. Based on these case studies the optimal tilt angle for the installation of PV plant can be selected focusing on the customer's choice and requirements. The on-grid system will be installed on the top of a 5 staired building. The coordinates of site where the study is conducted are 16.54° N and 81.50° E. The grid connected PV system with a capacity of 39.2 kWp is proposed based on the user's needs. The different field orientations of the PV panel namely fixed tilt, seasonal tilt and N-S axis tracking are defined briefly with losses. The performance of these on-grid photovoltaic systems during an entire year are analyzed and the performance parameters are measured. The data is analyzed by using the simulation software Pvsyst. The different parameters including efficiencies of module, inverter, array's initial yield, final array yield, and the performance ratio of PV system are analyzed for the 3 case studies.
In this paper, the performance of the four machine six bus system rotor angle with static synchronous compensator and different controllers like genetic power system stabilizer and multiband PSS have been analysed. By using STATCOM and multi band power system stabilizer, damping oscillations of the system rotor angle are improved which helps to improve efficiency of the power system network. It will be more effective for large power system network because cost of the STATCOM is high, so for small system it is costly as compared to SVC. Four generator systems is to be taken for the analysis of the generator rotor angle oscillations which is also called multi machine system. For this analysis we are using the software MATLAB/SIMULINK in which this model run and the outcome of the individual generator rotor angle response has been analysed. This four machine 6 bus systems are the reassembled model of the Western System Coordinated Council (WSCC). This multi machine system is analysed for different fault conditions like LG, LL, and LLG fault.
The increasing amount of renewable power generation systems is a challenging issue for the control and operation of the electrical networks. One of the main issues is lack of inertia, which is becoming a greater problem as much as the share of the power plants based on traditional synchronous generators gets reduced. In this regard, the new grid codes ask these plants to provide new functionalities such as the frequency support and inertia emulation. In this paper, a synchronous power controller for grid-connected converters is proposed as a good solution for the renewable generation systems with energy storage. It provides inertia, damping, and flexible droop characteristics. Different from the faithful replication of the swing equation of synchronous machines, an alternative control structure is proposed, by which the damping and inherent droop slope can be configured independently to meet the requirements in both dynamics and frequency regulations. Analysis and experimental results are both shown to validate the proposed controller.
