This paper presents a new mixed-integer linear programming (MILP) model to solve the multistage long-term expansion planning problem of electrical distribution systems (EDSs) considering the following alternatives: increasing the capacity of existing substations, constructing new substations, allocating capacitor banks and/or voltage regulators, constructing and/or reinforcing circuits, and modifying, if necessary, the system's topology. The aim is to minimize the investment and operation costs of the EDS over an established planning horizon. The proposed model uses a linearization technique and an approximation for transforming the original problem into an MILP model. The MILP model guarantees convergence to optimality by using existing classical optimization tools. In order to verify the efficiency of the proposed methodology, a 24-node test system was employed.

“…As shown in section 3, the most appropriate placement for a statcom device in a rural distribution network is at the end of the line as shown in Fig 24. The power rating of the statcom is calculated using the equations (6), (7), and (8) and a 1.3MVAR is used in the simulated scenario in order to maintain the voltage level of CT8 within limits. It can be seen that the STATCOM is able to maintain the voltage of the line within the established voltage limits and the dynamic response of the voltage control is better than with the SVR.…”

In rural distribution networks with widely dispersed loads, characterized by the utilization of long overhead lines, voltage profiles with big variations appear along the line due to the significant variations of the load between peak hours and valley hours.This paper describes the problems that the integration of distributed generation based on renewable resources could generate in that scenario, and presents solutions that are commonly used to mitigate these problems and proposes new solutions to solve them.The integration of distributed generation (DG) based on renewable resources in these networks increases the variability of the voltage, and in some cases the power flow of the network also can be bidirectional. Usually this integration of distributed generation is limited by the network operator limiting the maximum voltage variation produced by the distributed generation in the point of common coupling (PCC).In this paper different traditional methods for voltage control are described and analyzed for a widely dispersed rural network scenario.The impact of the DG in these methods of voltage control and the advantages of power electronics in this new scenario are exposed. Power Electronic devices applied to these distribution networks allow more efficient management of the network increasing the integration of distributed generation maintaining the security levels.

“…Especially, as one of the solution to the rising voltages due to the surplus energy of supplied power from PV, applying SVR has been considered. The optimal allocation and operation methods of SVR have been reported in the past [1][2][3][4][5]. However, it is thought that the load such as demand and PV generators would be further introduced in distribution network from now on.…”

Renewable energy resourses such as photovoltaic (PV) power and wind power have been installed in power networks as one of the countermeasures for global warming and depletion of fossil fuels. In particular, PV is the most promising of all renewable energy sources in Japan. However, the voltage may be risen due to the reverse power flow by connecting them to the distribution network. As one of the solutions for voltage problems due to the large scale penetration of PV generation, Voltage regulation by SVR (Step Voltage Regulator) has been expected. In this paper, we examine the optimal allocation and planning of the SVR for stabilizing voltages when PV generators are installed to a large extent into distribution networks. As a result, the voltage deviation can be reduced 84.5% on average with introducing a SVR. The optimal allocations are depended on capacities of PV generators. In addition, the voltage deviations are decreased 2.17% on average in every PV installation plan by replacement a SVR.
