A Sensitivity Analysis Toolkit for the Simplification of MV Distribution Network Voltage Management

Abstract: As distribution networks become increasingly variable and generation becomes increasingly decentralised, voltage standards are becoming more liable to violation. Accordingly, intelligent voltage management strategies are required to enable standards compliance without unduly increasing network maintenance or infrastructure costs. The relationship between network power and voltages, however, is complex, non-linear and interdependent, and thus is difficult to conceptualise and use for decision-making and control… Show more

“…5 the actual sensitivity factors are compared to the approximated sensitivities, where the influence of consumption of node 55 on the phase voltages of node 62 is presented. The actual sensitivity factors are calculated by the 'perturb-and-observe' method [2]. All households had an equal load, which ranged from -1 kW up to 1.5 kW to obtain the voltage sensitivity factors for different grid loading levels.…”

“…Voltage rise is normally the main limiting factor to prevent the increase of photovoltaic (PV) generation in LV networks [1], while a high penetration of electric vehicles (EVs) can result in significant voltage drops. Therefore, Distribution System Operators (DSOs) are discovering a need to develop and validate new voltage management strategies [2].…”

“…In [14], sensitivities of bus voltage magnitudes to load changes have been calculated using the adjoint-network method. In [15], a perturb-and-observe algorithm has been proposed to compensate voltage rises induced by distributed generators and to test siting and sizing of capacitors. Initial studies on the application of a closed-form solution of the Dist-Flow equations of an LV distribution system have been shown in [16,17].…”
