Local Power Grid Assessment of the Power System Expansion Considering Captive Power Plants

摘要

By considering the applied technology and load demand growth, a power system structure (PSS) becomes smartly huge networks that are consisted of many latest integrated parts and interconnected systems. Many local systems are expanded to a modern power system for increasing reliability and quality while delivering energy from generator sites to load demand areas. Recently, an environmental protection and a renewable energy source penetrate the PSS, which are subjected to reduce pollutant discharges and to increase the green potential energy source. This paper presents an operating assessment of the PSS based on a topology development of a local interconnection system and a captive power plant. These studies are used to evaluate the performances of the expanded local power grid whereas sun power plants are installed. In these works, the operating assessment is approached using a power flow study (PFS) for defining expanded structure performances. In addition, obtaining procedures are also facilitated with Takagi method (TM) and thunderstorm algorithm (TA) for a hybrid structure of the PFS considering an integrated renewable energy source (IRES). Based on technical scenarios, results show that the scenario is performed in differences. The case studies also give in various implications. The IRES have affected the system performances. The PSS contributes to the committed portion to cover the load. TM and TA can be applied to the hybrid structure of the PFS.
