“…To address this issue, a chance constraint is proposed in this paper to manage the risks of over-compensation. As shown in (21)- (22), the probability that economic benefit is greater than compensation should be larger than 1-ε (confidence level). Consequently, the per unit compensation πkc should be equal to the total compensation (i.e.…”

“…Reference [21] evaluates the operation and significance of energy storage considering the uncertainties of weather conditions. Reference [22] proposes a robust optimization based approach for optimal multi-microgrid operation in a residential scenario considering renewable energy uncertainties. Most of those works focus on the uncertainties in the optimal operation of microgrid.…”

“…D. Iteration-based chance-constrained method for flexible demand resource pricing As indicated by (22), the economic benefit is measured by the operation cost deviation between adopting or not adopting the incentive-based DSM program. It can be derived by calculating the deviation between two optimal values, which is quite complicated to be solved directly since it is an optimization problem with two minimization sub-problems.…”

With the rapidly increased penetration of renewable generations, incentive-based demand side management (DSM) shows great value on alleviating the uncertainty and providing flexibility for microgrid. However, how to price those demand resources becomes one of the most significant challenges for promoting incentive-based DSM under microgrid environments. In this paper, a flexible demand resource pricing scheme is proposed. Instead of using the utility function of end users like most existing literatures, the economic benefit of flexible demand resources is evaluated by the operation performance enhancement of microgrid and correspondingly the resource is priced based on a benefit sharing approach. An iteration-based chance-constrained method is established to calculate the economic benefit and shared compensation for demand resource providers. Meanwhile, the financial risks for the microgrid operator due to uncertain factors are mitigated by the chanceconstrained criterion. The proposed scheme is examined by an experimental microgrid to illustrate its effectiveness.Index Terms-Demand side management, resource pricing, renewable energy integration, microgrid, risk management

Microgrid energy systems are one of suitable solutions to the available problems in power systems such as energy losses, and resiliency issues. Local generation by these energy systems can reduce the role of the upstream network, which is a challenge in risky conditions. Also, uncertain behavior of electricity consumers and generating units can make the optimization problems sophisticated. So, uncertainty modeling seems to be necessary. In this paper, in order to model the uncertainty of generation of photovoltaic systems, a scenario-based model is used, while the robust optimization method is used to study the uncertainty of load. Moreover, the stochastic scheduling is performed to model the uncertain nature of renewable generation units. Time-of-use rates of demand response program (DRP) is also utilized to improve the system economic performance in different operating conditions. Studied problem is modeled using a mixed-integer linear programming (MILP). The general algebraic modeling system (GAMS) package is used to solve the proposed problem. A sample microgrid is studied and the results with DRP and without DRP are compared. It is shown that same robustness is achieved with a lower increase in the operation cost using DRP.

In this work, the impact of power exchange on reliability and economic indices of networked microgrids (MGs) is investigated. To this end, new reliability and economic indices are defined. The indices for emergencies in islanded and grid connected modes are evaluated. To increase the accuracy of simulation, a new evaluation method having a unique and precise answer is introduced. To optimize the customer interruption cost (CIC) reduction, the power exchange algorithm based on CIC reduction is presented. In this algorithm, the power exchange between MGs is carried out according to the cost of electricity and the value of the interrupted load. For this purpose, different scenarios of electricity prices are considered. To prove the efficiency of the proposed methods, these methods are tested on the well‐known distribution system bus 2 RBTS. Results reveal that the power exchange between MGs or MGs with grid can considerably affect the reliability and economic indices of MGs.
