This paper intends to consider a multi-objective problem for expansion planning in Power Distribution System (PDS) by focusing on (i) expansion strategy (ii) allocation of Circuit Breaker (CB), (iii) allocation of Distribution Static Compensator (DSTATCOM), (iv) Contingency Load Loss Index (CLLI), and power loss. Accordingly, the encoding parameters decide for expansion, Circuit Breaker (CB) placement, DSTATCOM placement, load of real and reactive powers of expanded bus or node are optimized using Grasshopper Optimization Algorithm (GOA) based on its distance and hence, the proposed algorithm is termed as Distance Oriented Grasshopper Optimization Algorithm (DGOA). The proposed expansion planning model is carried out in IEEE 33 test bus system. Moreover, the adopted scheme is compared with conventional algorithms and the optimal results are obtained.

AbstractCabled ocean observatories enabling large amounts of power and two-way communication bandwidth for underwater experiments are a future approach for studying the oceans. On April 21, 2011, at Monterey Bay, California, USA, a network node composed of a junction box (JBox) and three scientific instruments was deployed at the Monterey Accelerated Research System (MARS) site for a 6-month uninterrupted sea trial. The JBox is a facility that can provide multiple wet-mateable connections for various instruments. Each connection can draw 500 W of power and has 10/100 Mbit/s network communication. The current study presents the design and construction of the JBox with focus on the following aspects: a power distribution system with high reliability; a flexible springloaded mechanical structure for heat dissipation; communication that incorporates various data protocols; and self-protection against faults like over-current, short fault, ground fault, and flooding. The deployment and operation of the JBox is described. The sea trial results show that the technologies and methods applied on the JBox and the deploying approach are applicable and worthy of consideration for long-term cabled ocean observatories.
