Demand response (DR) can be very useful for an industrial facility, since it allows noticeable reductions in the electricity bill due to the significant value of energy demand. Although most industrial processes have stringent constraints in terms of hourly active power, DR only becomes attractive when performed with the contemporaneous use of battery(More)
A new short-term probabilistic forecasting method is proposed to predict the probability density function of the hourly active power generated by a photovoltaic system. Firstly, the probability density function of the hourly clearness index is forecasted making use of a Bayesian auto regressive time series model; the model takes into account the dependence(More)
The evolution of existing distribution systems toward smart grids requires the exploitation of all the capabilities of the new Distributed Generation (DG). To this aim, the present paper addresses the problem of improving the voltage profile regulation in distribution networks with DG. According to a decentralized approach, the set-point of a reactive power(More)
Radiation forecast accounting for daily and instantaneous variability was pursued by means of a new bi-parametric statistical model that builds on a model previously proposed by the same authors. The statistical model is developed with direct reference to the Liu-Jordan clear sky theoretical expression but is not bound by a specific clear sky model; it(More)
In the voltage regulation problem of MV distribution systems with Distributed Generation (DG), the regulator of the On Load Tap Changer (OLTC) equipped with Line Drop Compensator (LDC) interferes with the DG voltage regulator. This interaction can significantly changes the voltage profile along the feeders. With the aim to propose a solution to this(More)
The growth of penetration of Distributed Generators (DGs) is increasing the risk of unwanted islanded operation in Low Voltage (LV) distribution systems. In this scenario, the existing anti-islanding protection systems, installed at the DG premises and based on classical voltage and frequency relays, are no longer effective, especially in the cases of(More)
