Executive Summary : | Rapid depletion of fossil fuels, aging of conventional systems, ever increasing energy demand, concerns over climate change, and limitations of the transmission system are major driving forces leading to the renewable energy to the top of the energy portfolio. India is aiming to generate 100 GW of Solar power by the next year. But the large range of power systems was designed to transmit power from the conventional sources to the load. The transmission of power from renewable energy sources is posing a wide variety of challenges to electrical engineers. The PV system is a less inertial system since they use Power Electronics for the necessary conversion when integrated into the grid will weaken the system and reduce the Short Circuit Ratio (SCR) of the grid at the Point of Common coupling. The proposed project is designed to replicate the power system model. In this project, real-time power flow and regulation phenomena are considered by considering different generators and load patterns. It provides a solution for the issues pertaining to the large integration of solar power into the existing grid. The key findings of the project will be on effect on the operational features of the existing grid of our country India., effect on frequency regulation on the system (operation of governors of the thermal power plants), utilization of auxiliary sources as regulatory services, Effective utilization of large battery banks. The studies by various power agencies declare that the existing power plants should undergo frequent ramp-up and ramp-downs with the introduction of the sources. In this project, the stress on the conventional power plants is estimated by designing a simulation model in MATLAB. The following are the key considerations in this project. i. A 24 Hour Load pattern is considered in this project which is near to the Indian power scenario recorded by the POSOCO ii. Different conventional generators are considered whose inertia constant and other regulatory parameters are different iii. IEEE 14 Bus system is considered for the simulation Also, the utilization of the sources like Runoff power plants, Gas based power plants for the frequency regulation is shown in the project. To implement the project, a laboratory prototype is necessary which resembles the existing system. It includes a set of PV panels, Inverter, DSP controller, sensing boards, Two different Synchronous alternators, High precision digital oscilloscopes, measuring instruments, Passive filters, linear and non-linear loads. The work will give an immense boost for establishing a research center in the region in the area of study. I hope the results will be satisfying and the effects of integration can be understood thoroughly. It also gives the role of power electronics in maintaining the stability of the power system when intermittent sources are present. |
