Generation Expansion Planning Using Renewable Energy Sources with Storage

A vital component of maintaining economic growth is the development of the power infrastructure. Most power plants in India are powered by traditional energy sources such as coal, diesel, oil, gas, hydropower, and nuclear power. Numerous techniques for solving the models and resolving the efficiency issue have been put out in recent years. To create a realistic mathematical system and use GEP in the model solutions, the goal of this work is to analyze the GEP for the candidate system by integrating all important system components. The planning of the test system is done for two separate planning horizons, which are 6 and 14 years, respectively. For the same power system, GEP mathematical modeling studies are conducted to examine the effects of the addition of a solar power plant with a storage facility. Based on (a) the investment strategies of introducing solar plants as an alternative candidate plant or as a replacement for existing High Emission Plants (HEP), (b) whether the Solar Plant with Storage (SPWS) or Without Storage (SPWNS) capacity, and (c) inclusion of treatment/penalty costs on emissions from HEP, this is planned in a four-level hierarchy. For anticipated solar penetration levels of 5–10 and 10–20% for 6 and 14 years of planning horizons, respectively, the sensitivity of the system performance elements such as the capacity added, total cost, and Expected Energy Not Served (EENS) is also carried. The system’s performance is very dependent on the FOR% that is expected. When SPWS is added to the system as an alternative investment candidate plant, the model studies present an upbeat prospect for power system planning. This study offers a four-level hierarchy to understand the full range of policy issues that may arise in GEP and enables planners to implement situation-specific solutions, while also attempting to illustrate the complexity of the decision-making process when introducing solar plants into an existing system.
