Full text linkTo ensure sustainable development, the generation expansion planning (GEP) should meet the electricity demands in the specify time horizon. The GEP will determine the type and capacity of generator units to meet with the minimum cost, required reserve margin and energy balance. In this paper, a GEP to minimize the cost by considering the high penetration hydro energy potential was carried out in Sulawesi electricity region. GEP optimization is done by finding the minimum total cost value that is done through WASP-IV. There were two approaches for conducting the optimization that are regional balanced and resources-based approaches. The effect of renewable energy plant, especially the hydro energy, can be seen through a resource-based scenario, where the generating units were priories installed close to the energy source location. On the other hand, the regional balanced approach would install the generating units close to the load center. This paper compared the results of regional balance to the resource-based scenarios. The results show that resource-based approach can achieve a renewable energy power plant mix of up to 30%. The regional balance scenario total costs were 13.57 billion in high projection electricity demand. On the other hand, the resource-based scenario total costs were 13.38 billion high projection electricity demand
Battery energy storage system to reduce voltage rise under high penetration of customer-scale photovoltaics
No full textUnmanaged high penetration of customer-scale photovoltaic on the distribution network results in voltage rises along the network. However, the performance of the implemented battery energy storage system (BESS) to prevent voltage rise under that high penetration condition was unclear because the previous penetration models did not consider the intermittency and variability characteristics of the penetration due to their model simplifications. Therefore, this research proposes a BESS control scheme to mitigate impermissible voltage rises by considering the penetration characteristics of intermittency and variability. As a result, the proposed model outperformed the previous model by providing a more complete representation of the actual penetration issues, and thus the expected contribution of the BESS control scheme in reducing voltage rises could be provided
