Risk-Averse Model Predictive Operation Control of Islanded Microgrids

Abstract: In this paper we present a risk-averse model predictive control (MPC) scheme for the operation of islanded microgrids with very high share of renewable energy sources. The proposed scheme mitigates the effect of errors in the determination of the probability distribution of renewable infeed and load. This allows to use less complex and less accurate forecasting methods and to formulate low-dimensional scenariobased optimisation problems which are suitable for control applications. Additionally, the designer ma… Show more

“…Recently, MPC has been extended to solve the optimal load frequency control (LFC) problems of power systems [12][13][14][15][16] and operation optimization issues of microgrids [17][18][19][20]. Especially, it should be noted that there are some existing works regarding MPC-based frequency control of microgrids [12,[19][20][21][22][23]. Reference [12] developed a MPC-based coordinated load frequency control method for a microgrid under the condition regarding varied number of electric vehicles.…”

“…Risk-averse optimal control formulations are nowadays making their way in applications such as power systems [10], and economics [2] as their favorable properties are becoming evident. Yet, their applicability is hindered by their complexity and computational cost of associated multistage formulations.…”

“…When the system dynamics is linear (or affine) and functions t and φ t are convex in x and u, then (19) is a convex conic problem which can be solved very efficiently with solvers such as MOSEK [28], SuperSCS [29] and more. Problems (10) and (19) are equivalent in the sense that the optimal values of the objective function at the solution are the same. If all involved risk measures are strictly monotone, then the respective sets of minimizers are equal.…”
