This paper presents a binary PSO based solution technique for power system unit commitment. The intelligent generation of initial population and the repairing mechanism ensure feasible solution that satisfies the spinning reserve and unit minimum up/down constraints. The algorithm adoptively adjusts the inertia weight and the acceleration coefficients in order to enhance the search process and ...

This paper reports on work the Consortium for Electric Reliability Technology Solutions (CERTS) has been pursuing to hasten the arrival of meaningful load participation in competitive electricity markets. The activities include: experimental economic analysis of the effect of price responsive load in reducing market prices and price volatility; assessments of emerging demand response programs a...

Microgrid is commonly regarded as an efficient way for integration of distributed generation (DG) in low voltage network. However, the integration method of microgrid in power system for maximum benefit needs to be further promoted. In this paper, a stochastic bidding strategy of microgrid in a joint dayahead market of energy and spinning reserve service is proposed taking into account of uncer...

Ant colony optimization (ACO) which is inspired by the natural behavior of ants in finding the shortest path to food is appropriate for solving the combinatorial optimization problems. Therefore, it is used to solve the unit commitment problem (UCP) and attain the minimum cost for scheduling thermal units in order to produce the demand load. In this paper modified ACO (MACO) is used to solve th...

In this paper unit commitment problem (UCP) with spinning reserve and ramp rate constraint has been solved using Ant Colony System (ACS). In this model, foraging behavior of the real ants for finding its food from its start (nest) to its destination (food) is simulated to obtain the optimum solution. A search strategy has been adopted which involves the artificial ants to obtain the minimum cos...

Traditionally, conventional generation unit was used to provide ancillary services e.g. reactive power support, and spinning reserve. Nonetheless, with the emergence of highly penetrated distributed energy resources (DERs) systems and considering how beneficial they can be; it appears reasonable to use them as reactive power providers. Therefore, this paper introduces a new procedure for DERs t...
