Modern distribution systems are equipped with various distributed energy resources (DERs) because of the importance of local generation. These distribution systems encounter more and more uncertainties because of the ever-increasing use of renewable energies. Other sources of uncertainty, such as load variation and system components' failure, will intensify the unpredictable nature of modern distribution systems. Integrating energy storage systems into distribution grids can play a role as a flexible bidirectional source to accommodate issues from constantly varying loads and renewable resources. The overall functionality of these modern distribution systems is enhanced using communication and computational abilities in smart grid frameworks. Robust operation of these systems is effectively taken into consideration to manage the uncertainty, which offers an explicit way to control the desired conservativeness. This paper presents an optimal operating program for smart grids equipped with wind generators, controllable distributed generators, energy storage systems, and reactive power compensators. In order to make the studies more practical, uncertainty about wind generators and grid loads is taken into account. Furthermore, the presented operating program is robust in various conditions, i.e. there is no need to change the operating program in a wide range of probable states. The point estimation method and fuzzy clustering method are used for probabilistic assessment of the distribution system in the presence of uncertainties. The IEEE 37-node standard test system, which is a highly unbalanced system, is selected for the case study and the results are discussed comprehensively.

In this paper an exhaustive bibliographical revision of the mathematical methods used for the optimal selection and location of reactive power compensating elements is developed, the results obtained by different authors for different objective functions are analyzed and a scientific problem in the conflict that the electric variables show when analyzed individually is identified; thus demonstrating the need to analyze this problem in a multi-criteria way and taking into account topologies of distribution grids with distributed generation and energy storage. This research demonstrates that reactive power compensation in distribution grids with distributed resources is a problem that must be analyzed from multiple criteria that consider several objective functions to be optimized; thus achieving a global solution that contemplates an optimal location and dimensioning of reactive power compensating elements that contribute to the joint improvement of the voltage profiles, minimization of power losses, harmonic mitigation, increased line capacity, voltage stability and power factor improvement, all of them to a minimum investment cost. A theoretical heuristic is also proposed to solve the described problem, based on the multicriteria optimization method.

“…Karena penurunan signifikan terhadap bahan bakar fosil dan kekwatiran terhadap dampak hijau, maka saat ini seluruh dunia beralih ke sumber energi terbarukan seperti energi matahari, angin, laut, hydro, dan panas bumi [10][11][12]. Diantara sumber energi terbarukan yang ada, sumber energi matahari banyak dilirik oleh para insyinyur karena kinerjanya tidak mencemari lingkungan dalam menghasilkan listrik dan mampu memanen energi dari matahari, yang merupakan sumber energi bebas setelah fasilitas tersebut terpasang [13,14]. Sejak tahun 1970an negara Indonesia telah menerapkan sistem PV sebagai sumber tenaga listrik untuk di pulau-pulau kecil, namun pada tahun 1997 sempat berhenti karena terjadi krisis keuangan saat itu [15].…”

Makalah ini menyajikan sebuah metode aliran daya untuk memperkirakan lokasi penempatan pembangkit Photovoltaic (PV) yang optimal pada sistem distribusi. Metode ini sebagai metode untuk mengindentifikasi bus sistem yang paling sensitif. Pada Analisis dan simulasi ini dilakukan pada 44 bus, 47 line, dan 7 generator. Adapun efek penempatan PV yang tepat dengan metode Continuation Power Flow (CPF) adalah dapat meningkatkan profil tegangan dan dapat mengatasi ketidakstabilan tegangan, sehingga analisis dan evaluasi kestabilan tegangan dapat terlihat pada kondisi sebelum dan sesudah penambahan PV. Penelitian ini mengidentifikasi daerah-daerah yang memiliki radiasi matahari yang baik dari SOLARGIS data. Daerah yang memiliki irradiance yang baik menjadi input PV. Dari hasil analisa power flow menemukan daerah yang memiliki irradiance yang baik dan sensitivitas yang baik, dan bisa direkomendasikan untuk penempatan PV untuk membantu pelayanan beban yang semakin meningkat tiap tahunnya.
