Abstract
The policy transition towards renewable sources of energy generation has triggered a proliferation of small, independent, and decentralized power plants such as solar PV panels owned by households. This presents network operators with challenges regarding the maintenance and expansion of lowvoltage distribution grids. We model multiperiod planning of grid reinforcement on the basis of three investment strategies: a purely reactive strategy that disregards any information about the future, a proactive strategy that requires only a probability distribution of future distributed generation, and a hypothetical strategy assuming perfect information. Simulations show that 75% of the time the proactive strategy achieves equal or lower total reinforcement cost than the reactive strategy, which can be regarded as the industry standard. On average, it yields about 30% of theoretically possible savings. The results are robust to changing simulation parameters, including PV penetration levels.
