Based on current developments related to the application of technology and the growth of load demand, power system structure (PSS) has grown into a large, intelligent network by integrating many new systems. At present, many classical systems are being modernized and developed towards smart systems to various technical performances while providing continuously energy from the generating sites to serve load centres as end energy users. On the other hand, protection and attention to the environment and renewable energy sources also affect the power system operation which is intended to reduce emissions and include green energy sources. Furthermore, these works explore an assessment of operations on local interconnection system topologies which are installed captive power plants. These studies are used to develop and evaluate the performance, where solar power plants are also installed as sources of energy suppliers. In this study, operating assessments are approached using a power flow study (PFS) to define structural performance expanded through several scenarios. In addition, the procedure for obtaining optimal conditions is also facilitated by using the Takagi Method (TM) and Thunderstorm Algorithm (TA) for PFS hybrid structures considered an integrated renewable energy source (IRES). Based on the technical scenario set, the results show that the applied scenarios have different performances. In addition, this study also provides various implications. IRES has affected system performance. PSS contributes to the part that is committed to covering the burden. TM and TA can be applied to the hybrid PFS structure.

In principle, the power system (PS) is related to the process of converting primary energy sources and consumers as users of converted energy. So far, the energy conversion process has been carried out with applied technology which is now able to convert natural resources into a type of energy that can be used through a series of certain processes in the generating unit. On the other hand, power systems are prepared with various levels of electricity network services to form interconnection networks that connect generating units and load centers. In general, an integrated network power system (INPS) is widely used to integrate all sections , . At present, INPS is a large network and consists of complex integrated companies and operators to control operations -. In general, this system is used to maintain the availability and adequacy of sustainable energy as long as customers use utilities -. In addition, this network is also used to combine all generating units located close to various primary energy sources. In addition, this network is also connected to the load center at different distances for power delivery. Nowadays, the INPS is displayed by integrating a local power grid (LPG) to increase the guarantee of performances -. On the other hand, LPG continues to look for applied technologies as well as acceptable for the operation. Technically, LPG is operated in the classification structure which is used to supply power demands in accordance with the connections at backbone systems . In particular, customers are growing faster with increasing power demand, thus, it is requiring a different generation system area with the addition of a power plant. To cover this condition, the power balance must be acceptable for energy producers and users with a reasonable low cost -. Increased PS operation that is guaranteed based on LPG performance is an important aspect of the level of system de [...]
