“…The main challenges are determination of optimal locations and penetration levels of DG units which can easily be absorbed in the system without major structural changes while keeping all bus voltage levels within permissible limits. Even though DGs offer a variety of benefits, they may also impose some problems and limitations at high penetration levels such as overvoltage conditions and increased grid losses [2,5]. Most studies confirm that about 10 to 50% penetration of DG can be safely absorbed in the electricity network [6][7][8].…”

a b s t r a c tWe propose a pragmatic procedure to facilitate the connection process of Distributed Generation (DG) with reference to the European regulatory framework where Distribution System Operators (DSOs) are, except in specific cases, not allowed to own their generation. The procedure is termed Global Capacity ANnouncement (GCAN) and is intended to compute the estimates of maximum generation connection amount at appropriate substations in a distribution system, to help generation connection decisions. The pragmatism of the proposed procedure stems from its reliance on the tools that are routinely used in distribution systems planning and operation, and their use such that the possibilities of network sterilization are avoided. The tools involved include: long-term load forecasting, longterm planning of network extension/reinforcement, network reconfiguration, and power flow. Network sterilizing substations are identified through repeated power flow computations. The proposed procedure is supported by results using an artificially created 5-bus test system, the IEEE 33-bus test system, and a part of real-life distribution system of ORES (a Belgian DSO serving a large portion of the Walloon region in Belgium).

“…Such a relationship, expressed as the voltage sensitivity, provides a linear relation between voltage deviations and electrical quantities. The voltage-reactive power (V-Q) sensitivity is generally used for steady-state analyses of AC power systems, and V-Q sensitivity is often used in planning, operation, assessment, and control of power systems [10][11][12][13][14][15][16][17][18][19][20]. Moreover, voltage sensitivity can be utilized in medium-or low-voltage distribution networks with high penetrations of DERs, which underlines the importance of optimal control in a distribution network.…”

Formulation and Analysis of an Approximate Expression for Voltage Sensitivity in Radial DC Distribution Systems

Abstract:Voltage is an important variable that reflects system conditions in DC distribution systems and affects many characteristics of a system. In a DC distribution system, there is a close relationship between the real power and the voltage magnitude, and this is one of major differences from the characteristics of AC distribution systems. One such relationship is expressed as the voltage sensitivity, and an understanding of voltage sensitivity is very useful to describe DC distribution systems. In this paper, a formulation for a novel approximate expression for the voltage sensitivity in a radial DC distribution system is presented. The approximate expression is derived from the power flow equation with some additional assumptions. The results of approximate expression is compared with an exact calculation, and relations between the voltage sensitivity and electrical quantities are analyzed analytically using both the exact form and the approximate voltage sensitivity equation.
