Isolated power systems meet the electricity demand by generating power close to its point of utilisation. It is viewed as an option to electrify communities located in remote areas where extending the grid could be uneconomic. The principal design objective for such systems is the estimation of the ratings of the generators and the storage capacity requirements for meeting specified reliability...

Solving the problem of energy dispatch in a heterogeneous complex system is not a trivial task. The problem becomes even more complex considering uncertainties in demands and energy prices. This paper discusses the development of several Economic Model Predictive Control (EMPC) based strategies for solving an energy dispatch problem in a smart micro-grid. The smart grid components are described...

In this paper, an optimal energy management model for a RTG crane supplied by hybrid diesel generator/battery system is developed. The aim of the to reduce cost spending and CO2 emission minimizing amount fuel consumed generator, maximizing potential recovered through regenerative braking during container lowering phase. As case study, 40 tonnes operating in South Africa has been selected. dema...

This paper presents a hybrid photovoltaic (PV)-diesel management system performance analysis considering weather conditions. The is designed to operate based on charging current, battery capacity, and loading current. During current decreased but the capacity high, PV remains supplied for low medium When lowered in middle, still supplies However, when decreases voltage below 22.3 volts, supply ...

The supercapacitor characteristic of high-power delivery coupled with very fast charge/discharge cycles find its use in hybrid energy storage systems. In this paper, the bank is integrated small capacity lead-acid battery for development cost-effective system to crank vintage model diesel-generator. developed uses microcontroller-based controls active voltage balancing circuit reliable cranking...

There are methods of supplying the required energy to load while reducing cost relatively, but do not take into account amount reserved energy; this is preferred if batteries used store excess produced. The proposed method a mathematical model calculate system size for in an area far from electrical grid where there huge sources biomass and high rates solar radiation. includes three generate en...

The study of the operation power stations existing on ships shows need to ensure reliable parallel diesel generators (DGs). It is known that main reason for unstable DG a small or different droop mechanical characteristics drive motors. A generator sets at ship plant, consisting four with electronic speed controllers provide necessary droop, also showed its instability. measurements and conside...
