“…SIMULATION AND RESULTS To verify the applicability of the GA in optimal placement and sizing D-STATCOM problems, the proposed method is applied on the modified IEEE 16-bus test system shown in Fig. 3 [12]. The system is balanced and composed of several linear and non-linear loads with a total power of 2.73 MVA.…”

This paper presents a novel method to optimally place the Distribution Static Synchronous Compensator (D-STATCOM) in a distribution system using the firefly algorithm (FA) for enhancing power quality. In the proposed method, the average voltage total harmonic distortion (THD V ), average voltage deviation and total investment cost are considered as the objective functions, where voltage and power limits for individual buses are chosen as the optimization constraints. The performance of the proposed FA is investigated using the Matlab software on the radial IEEE 16bus test system. The obtained results are also compared with the particle swarm optimization and genetic algorithm. The simulation results verify the ability of FA in accurately determining the optimal location and size of the D-STATCOM in radial distribution systems.Index Terms-D-STATCOM, optimal placement, firefly algorithm, voltage sag

“…Table 1 lists some of these studies; several of them include THD/IHD analysis through on-site measurements during several time periods. PV system integration in low-voltage (LV) and medium-voltage (MV) networks can increase the Vrms and decrease the THDV at the PCC [9][10][11][16][17][18][19]21]; this effect seems to be more noticeable for higher PV power injections.…”

The intermittent injection of power and the nature of power electronic devices used for photovoltaic (PV) systems can affect the power quality (PQ) of the grid to which they are connected. This study proposes to quantify and evaluate the impact of PV injection on the PQ of a low-voltage (LV) network by applying a statistical analysis through hypothesis testing for the mean comparison of populations of parameters with and without a PV system. The effects of PV power injection and load demand at the point of common coupling on PQ are monitored. The methodology includes the selection and monitoring of PQ, the use of a matrix for classification of data with similar load and PV power injection conditions, and the application of the Wilcoxon rank sum test. This methodology was applied to evaluate the impact of a 9.8 kWp PV system on the PQ of an LV network.

“…These generations can be coupled in common DCbus or ACbus structure at each bus in EPS to become a microgrid. This microgrid can be operated in two ways: generating power from generations to EPS directly or being dispatched by any scenario as requirement of dispatchers [1][2][3][4].…”

“…In the first way, power generating to the grid varies continuously corresponding to the variation solar irradiance and wind speed [1]. This big disadvantage can be made difficult to dispatch power flow in whole EPS due to having to be absorbed big amount of power in daytime and or shortage a big amount of power in night-time.…”

This paper proposes a general demand-side management strategy in microgrids with the presence of renewable sources. To apply proposed above strategy by electric price in Vietnam, it must be participated of photovoltaic and wind power generations and energy storage. An algorithm applied for this program is created by comparing amount of energy generating from generations and consumed by electric load. Amount of energy that must be bought from the grid or sells to it can be calculated by dispatching energy between hours that have the lowest electric price level and hours that have the medium and highest electric price levels. A case study that energy generating from generations is not equal energy consumed by load in hours having the medium and highest electric price levels is made more detailed in this paper. Algorithms to dispatch energy at any time to achieve the purpose of not buying electricity from the grid in above hours basing on electric price levels, efficiency of energy conversion, rated capacity of units and analysis of power flows in whole system. Results providing from algorithms are energy that must be bought from the grid or sell to the grid, instantaneous capacity of energy storage. Simulation results corresponding to this case study carried out in MATLAB 2018a present the meaning and feasibility of proposed contents.
