Frequency control, as an ancillary service, is usually provided by generation reserves. In modern generating units the ramp rate limit can be selected; e.g. their ramp rate can be selected to be either normal or fast. In this paper, the impact of selecting the fast ramp rate of generating units on electricity price and its volatility is investigated in simultaneous scheduling of energy and prim...
In this paper, a comprehensive comparison of two distinct heuristic search approaches to solve the distribution switchin9 problem is presented. One approach is' based on a priority list of switches of the main search path defined by the feeder tie switch upstream to the substation. The other approach uses evaluation functions to address the problem. Evaluation functions are defined based on fee...
Channel allocation schemes in a mobile computing (wireless) environment can be either static or dynamic. Static allocation offers negligible channel acquisition time and zero message complexity and works well at a low system load; the performance steadily decreases as system load increases since many calls are dropped; in case of even temporary hot spots many calls may be dropped by a heavily l...
