This paper proposes a multi-objective benefit
function for operation of active distribution systems considering demand response program (DRP) and energy
storage system (ESS). In the active distribution system,
active network management (ANM) is applied so that the
distribution system equipment is controlled in real-time
status based on the real-time measurements of system
parameters (voltages and currents). The multi-objective
optimization problem is solved using e-constraint method,
and a fuzzy satisfying approach has been employed to
select the best compromise solution. Two different objective functions are considered as follows: benefit maximization of distribution company (DisCo); benefit
maximization of distributed generation owner (DGO). To
increase the benefits and efficient implementation of distributed generation (DG), DGO has installed battery as
energy storage system (ESS) in parallel with DG unit.
Consequently, DGO decides for the battery charging/discharging. DisCo has the ability to exchange energy with
the upstream network and DGO. Also, DisCo focuses to
study the effect of demand response program (DRP) on
total benefit function and consequently its influence on the
load profile has been discussed. This model is successfully
applied to a 33-bus radial distribution network.
