The article represents the research result on simulating mathematic calculation of electricity price at buses without distributed generation (DG) and with DG. The article aims at comparing the impact of DG on the electricity price at buses. The simulation results showed that when DG is integrated into the distribution network, the price signals are more efficient and the power losses reduce in the...
This paper proposes a new paradigm for distribution system operation under Active Network Management (ANM). The ANM method has essential role to facilitate the connection of new generations without need of reinforcement traditional network. This paper presents a cost function based on active management that minimize energy cost of Distribution Network Operator (DNO). The proposed objective function...
Optimal power flow (OPF) problem is to optimize an objective function (usually total cost of generation), while satisfying system constraints. The OPF is a non-linear and non-convex problem, and an artificial bee colony (ABC) algorithm is utilized to handle the problem. Heuristic methods are credited for their simplicity to solve complex non-linear optimization problem without simplifying approximation...
This paper proposes a new paradigm for distribution system operation with considering Demand Response Programs (DRP). In this paper is focused to study the effect of DRP on total cost function, where the time-based demand response programs have been modeled and consequently its influence on load profile has been discussed. This paper presents a cost function that minimizes energy cost of Distribution...
One of the main aims of distribution networks is increasing the participation of distributed generation. One of the methods that can determine the maximum penetration of DG in distribution network is use of active network management. Active network management has essential role to facilitate the connection of new generations without need of reinforcement traditional network. This paper proposes a...
The paper presents an integrated framework to analyze the issues of reactive power planning along with reactive power pricing. The planning problem involves optimal placement and sizing of capacitors in a network such that operating and investment costs are minimum. A simple bus-wise cost-benefit analysis (CBA) scheme is proposed which involves solving a modified optimal power flow problem (OPF) iteratively...
